TLDR
This paper presents a new development of the distributed-index planar microlens of 2.5-3-mm focal length and 0.15 N.A. and shows that it is usable with optical components in fiber communications and proposes a concept of stacked planar optics consisting of a stack of arrayed planarmicrolenses and other optical components.Abstract:
In this paper we present a new development of the distributed-index planar microlens of 2.5-3-mm focal length and 0.15 N.A. and also show that it is usable with optical components in fiber communications. We then propose a concept of stacked planar optics consisting of a stack of arrayed planar microlenses and other optical components. From this configuration a 2-D array of optical devices is monolithically available, and many discrete components can be separated from the array. An optical tap array has been fabricated as an example of stacked planar optics.read more

Micro-optic devices for fiber-optic communications
TL;DR: In this article, the beam transformation in a graded index rod (beam undulation and beam size change), in association with reflection or refraction at a grade index rod facet, is proposed to realize coupling/branching in fiber-optic communications.
