Abstract

Recently we demonstrated a novel type of hybrid silicon laser based on resonant grating cavity mirrors. The first optically-pumped proof-of-principle device measures 2μm by 55μm, requires milliWatt-level threshold power and has a side-mode suppression ratio of 39 dB. In this work we discuss the challenges and propose a scheme for porting the concept to an electrically pumped device. The novel implementation combines a high-Q cavity with an advanced III-V waveguide design to reach the same properties as the demonstrated optically pumped laser.
