`
`Career Synopsis
`
`My 20 year research career in optical communications started during
`
`my Master’s degree, where I investigated free-space, polarization rotation based
`
`bypass-exchange (2×2) space switches, which later on led to the founding of a
`
`start-up company (without my involvement). In my doctoral dissertation I
`
`demonstrated real-time optical signal processing using parametric nonlinearities

`
`applied to spectrally dispersed light, for possible modulation and detection
`
`schemes in serial ultrafast communications (tera-baud rate and beyond). From
`
`2000 until 2005, I was a Member of the Technical Staff at the Advanced Photonics
`
`Research Department of Bell Laboratories, Lucent Technologies, where I invented
`
`MEMS based wavelength-selective switching solutions for optical networks and
`
`headed the research and development effort of these solutions. Since 2005, I have
`
`been with the Applied Physics Department, Hebrew University, Israel, where I am
`
`now an Associate Professor leading a research group pursuing my research
`
`interests in creating photonic devices and sub-systems for switching and
`
`manipulating optical signals, in guided-wave and free-space optics solutions using
`
`light modulating devices, nonlinear optics, and compound materials.
`

`
`Career Milestones
`
`I am a Senior Member of the IEEE Photonics Society, and a Member
`
`of the Optical Society of America. From 1996 through 2000, I was a Fannie and
`
`John Hertz Foundation Graduate Fellow at UCSD, and was a Peter Brojde Scholar
`
`in 2006-2007. I currently serve as Senior Editor for IEEE Photonics Technology

`
`Detailed Research Activity
`
`5.
`
`The following paragraphs describe in more detail some of the research
`
`work I have been involved in. Much of this research involves areas of technology
`
`that are directly related to the subject matter of the patent at issue in this IPR.
`
`Spectral processing of ultrafast waveforms with parametric nonlinearities:
`
`During my Ph.D, studies (1995-2000), I experimentally developed and
`
`theoretically analyzed the operating principles of spatio-temporal wave-mixing
`
`arranging, demonstrating time-to-space, space-to-time, time-reversal, temporal and
`
`spatial correlators, all based on instantaneous nonlinearities. Select publications in
`
`this area include:

`As a Member of the Technical Staff at Bell Labs’ Photonics Lab
`
`(2000-2005), I initiated and led the complete Bell Labs development effort of the
`
`wavelength-selective switch, including acting as an inventor in these efforts. In
`
`addition, the hybrid integration of arrayed waveguide gratings into a free-space
`
`WSS was demonstrated, as well as off-shoot projects in dispersion compensation
`
`and optimal signal restoration after wavelength conversion.

`Time-to-space conversion: After devoting about ten years in this
`
`research track, during which time I focused mostly on WSS activities, I returned to
`
`this research topic and have injected into my activity photonics knowhow gained in
`
`WDM spectral processors, addressing the resolution-efficiency tradeoff by way of
`
`engineering the nonlinear interaction medium. The latest result demonstrated
`
`direct, complex-amplitude temporal waveform recording by interferogram image

`
`filing date and in light of the specification and file history of the ‘368 patent. I will
`
`refer to such a person as a "PHOSITA."
`
`17.
`
`For the relevant priority date for the ‘368 patent, I have used in my
`
`declaration the earliest application date on the face of the patent: Mar. 19, 2001.
`
`However, I have not yet analyzed whether the ‘368 patent is entitled to that date
`
`for its priority.
`
`18. Counsel has advised me that to determine the appropriate level of one
`
`of ordinary skill in the art, the following four factors may be considered: (a) the
`
`types of problems encountered by those working in the field and prior art solutions
`
`thereto; (b) the sophistication of the technology in question, and the rapidity with
`
`which innovations occur in the field; (c) the educational level of active workers in
`
`the field; and (d) the educational level of the inventor.
`
`19. With over 20 years of experience in electrical engineering and in
`
`optical communications, I am well acquainted with the level of ordinary skill
`
`required to implement the subject matter of the ‘368 patent. I have direct

`
`experience with and am capable of rendering an informed opinion on what the
`
`level of ordinary skill in the art was for the relevant field as of March 2001.
`
`20.
`
`The relevant technology field for the ‘368 patent is free-space
`
`photonic switching sub-systems, a field related to free-space optics. Based on this,
`
`and the four factors above, it is my opinion that PHOSITA would have been an
`
`engineer or physicist with at least a Master’s degree, or equivalent experience, in
`
`optics, physics, electrical engineering, or a related field, including at least three
`
`years of additional experience designing, constructing, and/or testing optical
`
`systems.
`
`21. My analysis and opinions regarding the '368 patent have been based
`
`on the perspective of a person of ordinary skill in the art as of March 2001.
`
`B.
`
`22.
`
`Prior Art
`
`I understand that the law provides categories of information that
`
`constitute prior art that may be used to anticipate or render obvious patent claims.
`
`To be prior art to a particular patent claim under the relevant law, I understand that
`
`a reference must have been made, known used, published, or patented, or be the
`
`subject of a patent application by another, before the priority date of the patent. I
`
`also understand that the PHOSITA is presumed to have knowledge of the relevant
`
`14
`
`prior art.

`
`Broadest Reasonable Interpretations
`
`I understand that, in Inter Partes Review, the claim terms are to be
`
`given their broadest reasonable interpretation (BRI) in light of the specification.
`
`See 37 C.F.R. § 42.100(b). In performing my analysis and rendering my opinions,
`
`I have interpreted claim terms for which the Petitioner has not proposed a BRI

`
`construction by giving them the ordinary meaning they would have to a the
`
`PHOSITA, reading the (cid:1932)368 Patent with its priority filing date (March 19, 2001) in
`
`mind, and in light of its specification and file history.
`
`24.
`
`I understand that the Petitioner has made determinations about the
`
`broadest reasonable interpretations of several of the claim terms in the ‘368 patent.
`
`I have identified these BRIs in Table 2, below.

`25. My analysis in this declaration assumes that the terms in Table 2,
`
`above, are defined using the associated BRIs. From my reading of the ‘368 patent,
`
`I believe that these BRIs are consistent with how one of skill in the art at the time
`
`the ‘368 patent was filed would interpret the claim terms. The Petitioner has
`
`determined that the BRIs of several of the terms in the ‘368 patent are not limiting.
`
`However, I am providing analysis in my declaration showing that even if the terms
`
`are limiting, the associated claim elements are disclosed in the prior art.
`
`III. THE ‘368 PATENT
`
`26. As indicated on its face, the ‘368 patent reissued from U.S. reissue
`
`patent application No. 12/816,084 on June 15, 2010, is a reissue of U.S. patent No.
`
`6,879,750. The ‘368 patent claims priority to U.S. provisional application No.
`
`60/277.217, filed on March 19, 2001. The ‘368 patent reissued on May 17, 2011.
`
`27. As its title indicates, the '368 patent relates to reconfigurable optical
`
`add-drop multiplexers (ROADMs). (Id., Title (“RECONFIGURABLE OPTICAL
`
`ADD-DROP Multiplexers WITH SERVO CONTROL AND DYNAMIC
`

`
`

`

`
`SPECTRAL POWER MANAGEMENT CAPABILITIES”).) More specifically,
`
`the ‘368 patent describes "a wavelength-separating routing (WSR) apparatus and
`
`method" (Id. at Abstract), which separates a multi-wavelength optical signal into
`
`separate channels and directs selected channels into selected output ports.
`
`IV.
`
`STATE OF THE ART OF THE RELEVANT TECHNOLOGY AT
`THE TIME OF THE ALLEGED INVENTION
`
`A.
`
`28.
`
`Reconfigurable Optical Add-Drop Multiplexers
`
`Early optical wavelength-division multiplexed (WDM) networks had
`
`fixed wavelength channel optical add drop multiplexers (OADMs), in order for
`
`information to be accessible at the network node. A basic OADM sub-system has
`
`four fiber ports, with one ‘input’ fiber port for receiving a WDM signal, a ‘drop’
`
`fiber port where the WDM channel that is configured to be dropped will emerge,
`
`an ‘add’ fiber port where the replacement WDM channel will be introduced, and
`
`an ‘output’ fiber port for the complete WDM signal (including the replaced
`
`channel) which will lead back to the optical network for transmission to the next
`
`node. For example, a WDM add/drop multiplexer from before the filing date of
`
`the ‘368 patent is shown symbolically below:

`Exhibit 1029, Page 20

`
`Multiplexer for Lightwave Communication Networks, Bell Labs Technical Journal,
`
`(Jan.-Mar. 1999) at 210). OADMs were sometimes implemented by using fixed
`
`filters to extract a single wavelength channel.
`
`29.
`
`For greater flexibility in optical network operation, a reconfigurable
`
`OADM (a ROADM) was useful to enable network traffic to grow without
`
`requiring manual hardware changes. Different implementations of ROADMs were
`
`known at the filing date for the ‘368 patent. (See, e.g., [Ex. 1017], U.S. Patent No.
`
`6,204,946

`
`wavelength division multiplex add/drop device using micromirrors”); [Ex. 1022],

`
`Publication No. US 2002/0105692 to Lauder et al., p. 4, Fig. 11.)
`
`30.
`
`I personally worked on ROADMs as early as May 2000, when I
`
`joined the Advanced Photonics Research Department of Bell Labs.
`
`B. Wavelength Selective Switches
`
`31. One implementation of ROADMs uses wavelength-selective switches
`
`(WSS). WSS is the established category name today for switches that operate on a
`
`multi-wavelength optical signal but whose switching function can be tailored per
`
`wavelength channel. Circa year 2000 there were a few other names for devices that
`
`performed such switching functions such as Wavelength-Routing Switch (or WRS;
`
`see [Ex. 1032], Borella, et al., Optical Components for WDM Lightwave Networks,
`
`Proceedings of the IEEE, Vol. 85, NO. 8, August 1997 (“Borella”) at
`
`pp.1292,1300), and Wavelength-Selective Router (or WSR; see [Ex. 1026], U.S.
`
`Patent No. 5,875,272 to Kewitsch et al. (“Kewitsch”)) at Abstract, 4:15-25). Such
`
`conventions as WSR and WRS are now referred to as WSS without loss of
`
`generality. WSS can be constructed using various methods and technologies, but in
`
`the matter of the ‘368 patent, the WSS is implemented in free-space (as opposed to
`
`light guided implementations), using the light radiating out of the transmission
`
`optical fiber at the switch input port, and spatially separating this WDM light beam

`into individual beams using a dispersive optics arrangement (similar to an optical
`
`spectrometer). In this arrangement, each beam corresponds to an individual

`channel
