- W2078273889 abstract "4 μm stripe ridge waveguide InGaAsN lasers were processed. Pulsed (10 μs, 1% duty) emission was up to 240 mW at 20 °C and 20 mW at 120 °C. The emission wavelength is around 1260 nm at RT. The threshold is 15 mA at 20 °C, corresponding to a threshold current density of 313 A/cm2. For CW operation, the lasers show a very low threshold of 23 mA and the maximum output was up to 40 mW for a 1200 μm length chip at RT. All the emission described was kink-free and single-mode. The laser with broad area (40 μm stripe width) processing using the same material has been working under CW operation at constant current (80% of maximum output) for more than 15 500 device-hours at 30 °C and is still working well." @default.
