1 October 2003 High fill-factor avalanche photodetectors for near-infrared free-space photonic networks

Diffractive optical elements (DOEs) offer the ability to boost fill factors of high-speed (field-of-view limited) near-infrared detectors. In this context, we have investigated the design and fabrication of a system that involves integration of DOEs with avalanche photodetectors (APDs). These APDs are implemented in the antimonide material system for operation around a 2.1-μm wavelength. Consequently, such systems could be used to reduce the required threshold power at free-space photonic receivers. To this end, we present the design and fabrication technologies for the DOEs, APDs, and their integration using polymer-based flip-chip interconnections.
