Abstract :
Toward realization of an ultralow-power-consumption semiconductor light source for optical interconnection, we have been investigating the lateral current injection (LCI) membrane distributed feedback (DFB) laser. This time, we realized membrane Fabry-Perot (FP) laser with 220 nm core thickness and demonstrated room-temperature continuous-wave (CW) operation with a threshold current of 3.5 mA for the cavity length of 700 μm and the stripe width of 1.0 μm, which is almost the same as the theoretical value.
