Abstract

In this paper we present free-space micro-optics coupling results for 10 Gb/s avalanche photodiode (APD) receivers. A free-space micro-optics approach provides compact cost-effective coupling with minimum insertion loss. Both DC and high frequency (RF) coupling characteristics are presented, and respective dimensions of the photosensitive areas are calculated. Effects of both axial and lateral misalignments on 10 Gb/s APD performance are presented. An analytical model for the photosensitive area of 10 Gb/s APDs is developed based on the RF coupling performance and can be used in optical design and opto-mechanical tolerance analysis. It is shown that free-space micro-optics coupling of APDs enlarges the effective size of the photosensitive area for achieving good RF device performance and provides robust packaging of 10 Gb/s APD receivers.
