Characterization of photoreceivers used in lightwave instrumentation

Abstract

"Photoreceiver" is a general term describing a photodiode and associated control and processing electronics, used for optical-to-electrical conversion. Photoreceivers take the form of power meters, optical spectrum analyzers, telecommunication receiving systems, and many other instruments. Numerous specialized tests exist for photoreceivers, but this paper discusses five fundamental tests with broad applicability. These tests are spectral responsivity, dynamic accuracy, packaging structure, frequency responsivity, and polarization sensitivity. Emphasis is on procedures likely to be used for fiberoptic telecommunication test instruments, using standards obtained from NIST.<>
