Abstract

Indium gallium arsenide (InGaAs) photodiode arrays are used in a wide variety of optical communications-related applications. Two-dimensional arrays are used for laser beam profiling, assembly and performance monitoring of optical switches and add-drop multiplexers, and simultaneous aiming/detection for free space communications. Linear arrays integrated with self- scanned readout integrated circuits are used for the spectroscopic monitoring of WDM source arrays and for dynamic gain flattening of erbium-doped fiber amplifiers (EDFAs). Parallel output arrays are coupled with arrayed waveguide gratings (AWGs) both for power monitoring of WDM source arrays and direct detection of high-speed signals. In this paper we will summarize the status of InGaAs array technology and describe the various applications in detail.
