Abstract

This letter presents highly polarized edge light-emitting diodes with high-confinement, strained, multiple quantum-well active regions. We demonstrate +40 dB of polarization extinction along with 16 dBm of output power from an 800-mum-long centered quantum-well device. By characterizing the polarization extinction and gain of devices with different lengths and optical confinement, we show that the polarization extinction is dominated by the polarization sensitivity of the gain
