"On-Wafer" Surface Implanted High Power, Picosecond Pulse Ingaasp/Inp (Lambda=1.53-1.55 Mu M) Laser Diodes

A cost-effective, on-wafer surface implantation technique was applied for the fabrication of short pulse InGaAsP/InP laser diodes. Based on thick electroplated Au masks, local ion implantation could be performed, allowing a versatile design of the absorber region. Picosecond pulses with typical FWHM of 20 ps and optical power exceeding 1.8 W were obtained. The measured emission spectrum in the pulsed regime demonstrates the potential of such devices to pump commercially available EDFA's.
