Abstract

Detrimental surface recombination of carriers in InP-based photonic crystal nanobeams containing quantum wells is reduced by employing chemical treatment followed by silica encapsulation. Carrier lifetime is shown to recover to 2.63ns close to the bulk value. This enables us to obtain optically pumped room-temperature continuous-wave nanolasers at 1.55µm integrated onto Silicon on insulator waveguide platform with a threshold of 8µW.

摘要

通过采用化学处理并随后进行二氧化硅封装，可减少含量子阱的基于磷化铟的光子晶体纳米光束中载流子的有害表面复合。载流子寿命恢复到接近体材料值的2.63纳秒。这使我们能够在绝缘体上硅波导平台上获得集成的1.55微米光泵浦室温连续波纳米激光器，其阈值为8微瓦。
