INTEGRATED MONITORING AND FEEDBACK DESIGNS FOR EXTERNAL CAVITY TUNABLE LASERS

摘要

An integrated structure includes front and rear facets (201, 203) optically- coupled by a waveguide (220) passing through the integrated structure. The integrated structure includes a gain section (202) and a reflector (208) optically coupled to the gain section by the waveguide, the reflector to emit an optical output. A modulator (214) is optically coupled to the reflector by the waveguide, the modulator to modulate the optical output. And a control section (216) disposed along the waveguide.
