Abstract

A high precision reflectometer for probing of localized reflections in photonic devices and circuits on InP was described. The reflectometer employed was the Michelson interferometer equipped with two low-coherence light probes. The optical and opto-electronic quality of the cavity were investigated through the transmitted probe light and the edge-electroluninescence from the device under carrier injection. This ivestigation led to the precise location of the unknown reflection. The recording of edge-electroluminescence spectrum from the test device provided the access to the opto-electronic quality of the guiding layer and the carrier combination properties of a center.
