Light Coupling Characteristics of a Planar Microlens.

The two-dimensional (2-D) integrated planar microlens (PML) is expected to be used in connection with various 2-D devices in parallel optical fiber communication systems. In this paper, we demonstrate recent progresses made for PML and its light coupling Characteristics. The coupling characteristics between (1) LD and single-mode fiber, (2) LED and GI-50 fiber, (3) single-mode fiber and single-mode fiber, and (4) single-mode fiber and detector were evaluated. In this paper, we evaluate coupling characteristics corresponding to single lens in an array. [ABSTRACT FROM AUTHOR]
