OPTICAL SYSTEM WITH INTEGRATED PHOTODETECTORS

摘要

An optical system and a method of fabrication are provided. The optical system includes a substrate and at least one hole extending from a second side of the substrate towards a first side of the substrate and configured to receive at least one optical fiber. The substrate includes at least one photodetector at the first side or between the at least one hole and the first side and configured to be in an optical path of an optical signal emitted from the at least one optical fiber or transmitted through the first side to the at least one optical fiber. The at least one photodetector is responsive to the optical signal by generating an electrical signal indicative of an intensity of the optical signal
