High output power single longitudinal mode graded index separate confinement multiple quantum well InGaAs/InP distributed feedback (GRIN SCH MQW DFB) lasers

A high continuous-wave (CW) output and high quantum efficiency of 1.5 mu m-wavelength InGaAs/InP graded-index separate-confinement multiple-quantum-well DFB lasers were demonstrated. A threshold current of 45 mA with a maximum output power close to 100 mW and a quantum efficiency of 0.33 mW/mA was o...

More Information
Summary:A high continuous-wave (CW) output and high quantum efficiency of 1.5 mu m-wavelength InGaAs/InP graded-index separate-confinement multiple-quantum-well DFB lasers were demonstrated. A threshold current of 45 mA with a maximum output power close to 100 mW and a quantum efficiency of 0.33 mW/mA was obtained. Single-frequency light output with power as high as 16 dBm (40 mW) was launched into a single-mode fiber.< >
