Photodiode array for characterizing optical fibers

An innovative approach is proposed and demonstrated for measuring the attenuation of light in optical fibers. The technique utilizes a silicon device containing a v-groove that positions the fiber and detector array along the v-groove. The detectors within the v-groove are designed to partially surr...

Zusammenfassung:An innovative approach is proposed and demonstrated for measuring the attenuation of light in optical fibers. The technique utilizes a silicon device containing a v-groove that positions the fiber and detector array along the v-groove. The detectors within the v-groove are designed to partially surround the fiber in order to maximize the coupling of scattered light from the fiber into each detector.
