摘要
It is reported on realization of pulsed operation of InGaAs/InGaAlAs straincompensated multiple-quantum-well lasers at room temperatures. The working wavelength is 1. 56μm; the threshold current density for the stripe waveguide lasers is less than 1. 85kA/cm2; for the ridge waveguide lasers, the threshold current is 35 mA. The incorporation of compensated strain, which makes the multiple-quantum-well design applicable, leads to an obvious improvement on device temperature characteristic.
