High Power, Locker-Free, Compact Hybrid Integrated Tunable Laser
We demonstrate a compact, high power tunable laser based on free-space hybrid integration of indium phosphide gain chips with thermally tuned low loss silicon etalons. By optimization of filter fabrication and laser cavity design we achieve 17.6 dBm output power. Integrated thermal control elements enable accurate and wide tuning without the typical external optical feedback or wavelength locking components.
