Abstract :
The use of a thick quantum well enables coherence-collapse operation of a Bragg grating stabilised laser diode over 110°C temperature range, yielding 975 nm wavelength emission with >40 dB sidemode suppression ratio, <1% power variation, and fibre-output power as high as 293 mW at 15°C and 168 mW at 125°C.
