Measurements on degraded devices show increased optical mode loss is responsible for degradation and a consequent shortening of lasing wavelength. %A S Shutts %A CP Allford %A C Spinnler %A Z Li %A M Tang %A H Liu %A PM Smowton %B Proceedings of the 2018 IEEE International Semiconductor Laser Conference (ISLC) %P 85-86 %I IEEE
