Long wavelength (1.02-1.03 /spl mu/m) InGaAs/GaAs lasers fabricated by MBE

The operation of InGaAs/GaAs SCH SQW lasers emitting at the wavelength 1.02-1.03 /spl mu/m, fabricated by MBE technology, is reported. Longer wavelength of emission was achieved by applying high indium content in the active region. The paper presents characteristics of fabricated structures measured at room temperature (T=300 K) under pulsed operation. The results are promising and give hope for fabricating structures emitting at 1.06 /spl mu/m, which in some applications could replace diode pumped Nd:YAG lasers.
