A lateral current injection laser with a thin (400 nm) core structure grown on a semi-insulating InP substrate was realized and a room-temperature (RT) pulsed operation was obtained. A threshold current of 105 mA, which corresponds to a threshold current density of 1.3 kA/cm2, was obtained for a 1.47 mm long Fabry-Perot cavity laser.
