Very-low-threshold current density continuous-wave quantum-dot laser diode
Abbreviated Journal Title
Engineering, Electrical & Electronic
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/cm(2). The broad-area laser diode operates at a wavelength of 1.22 mu 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 similar to 6A/cm(2).
