Abstract
We demonstrate a single mode 940nm VCSEL with a five-junction bipolar cascade active region. The device achieves 11 mW output power and 44 dB sidemode suppression ratio under continuous wave, room temperature operation. Peak power conversion and slope efficiency are 51% and 5.4 W/ A, respectively.
