INTEGRATED MONITORING AND FEEDBACK DESIGNS FOR EXTERNAL CAVITY TUNABLE LASERS

摘要

integrated structure is optically coupled to the front and back by a waveguide 220 through the integrated structure, (201, 203), and the. Integrated structure includes a gain section 202, and reflector 208 optically coupled to the gain section by the waveguide, the reflector to emit an optical output. Modulator 214 is optically coupled to the reflector by the waveguide, the modulator to modulate the light output. The control unit 216 thus is arranged to waveguides.
