Abstract

We present novel 1550 nm InGaAsP MQW based broad area single emitters with 100 μm stripe width showing 4.9 W CW output power at 20 °C operation temperature and a maximum wall plug efficiency of 40%. An optimized low loss large optical cavity design has been used, allowing for a narrow optical far-field of 25° x 15°FHWM. Furthermore respective wavelength stabilized lasers have been realized.
