Abstract

Robust and efficient optical coupling from laser-to-fiber and from fiber-to-detector is an important consideration for loss limited optical data links. Standard chip scale package process flow used by the semiconductor industry is based upon machine vision assisted "pick-and-place" die attach and wirebonding operations. To realize scalable heterogeneous integration of optical elements, mass production must be done within the framework of existing manufacturing equipment and avoid active opto-mechanical alignment steps. This publication reports on the performance of a set of a refractive, hemi-aspheric, nonimaging optical concentrators that are simple and amenable to standard package integration flow with passive alignment. A set of lenses are made by single-point diamond-turning and injection molding of unfilled polyetherimide, which is relatively transparent at the link operating wavelength of 850 nm. The goal of the design is to balance the absolute coupling at optimum alignment with wide margins for angular and linear misalignment.
