`the light going out of the fibers must be collimeted using
`microlenses to inipmve the efficiency. A marbles: array in
`which micmlenses are arrayed. accurately in the same way as
`in a fiber array is shown in Figure 9.26.

`
`Mir-Milena arrays include graded index lenses fabricated by
`ion exchange of glass“; lenses obtained by transferring a
`resist pattern that exhibits a spherical shape by resist refluw
