Integrated optical device with wavelength selective switching and method of fabrication

摘要

Optical source comprises two coupling components of Bragg gratings (14), first (v1) and second (v2) access routes to the coupling component, formed on a single substrate, allowing transmission of wavelength switching of input signals (V1) to one of two output channels (V3,V4). External laser cavity (1) and the coupler are symmetrical to Bragg gratings (11,11a,11b), which are formed in same substrate (16).
