InGaAsP/InP strained MQW laser with integrated mode size converter using the shadow masked growth technique

We have successfully integrated a mode size converter with a PBH strained MQW InGaAsP/InP laser diode using the SMG technique. The laser performance is hardly affected by the taper integration. Due to the taper, the coupling loss to a cleaved fibre is reduced from 9.3 dB for a non-tapered laser to 3.3 dB for a laser with a 200 /spl mu/m taper.
