1.5 /spl mu/m InGaAsP/InP large mode size laser for high coupling efficiency to cleaved single mode fibre

Increased mode size MQW BH lasers utilising a tapered active region and passive guide have shown cleaved fibre coupling losses down to 4.1 dB with threshold currents of 4.9 mA and 15 mA at 20/spl deg/C and 80/spl deg/C respectively.
