摘要
En 中文
Single longitudinal mode operation of an InGaP/GaAs/InGaAs quantum well heterojunction bipolar transistor laser is reported. A third order distributed feedback surface grating is fabricated in the top emitter AlGaAs confining layers using soft photocurable nanoimprint lithography. The device produces continuous wave laser operation with a peak wavelength lambda=959.75 nm and threshold current I(B)=13 mA operating at -70 degrees C. For devices with cleaved ends a sidemode suppression ratio >25 dB has been achieved. (C) 2010 American Institute of Physics. [doi:10.1063/1.3453656]
