Title
Very-Low-Threshold Current Density Continuous-Wave Quantum-Dot Laser Diode
Abstract
Data are presented showing that a quantum-dot laser diode can achieve a continuous-wave room-temperature threshold current density as low as 11.7 A/cm2. The broad-area laser diode operates at a wavelength of 1.22 m and delivers a power level of 0.42 W with 40 maximum slope efficiency in p-up mounting without heatsinking. Spectral measurements indicate the onset of stimulated emission at ∼6 A/cm2. © 2008 The Institution of Engineering and Technology.
