Hybrid External Cavity Laser with an Amorphous Silicon-Based Photonic Crystal Cavity Mirror

摘要： The authors present results on the performance of a hybrid external cavity photonic crystal laser-comprising semiconductor optical ampli?er, and a 2D photonic crystal cavity fabricated in low-temperature amorphous silicon. The authors demonstrate that lithographic control over amorphous silicon photonic crystal cavity-resonant wavelengths is possible, and that single-mode lasing at optical telecommunications wavelengths is possible on an amorphous silicon platform.
