Abstract :
We present a study of dual-wavelength optically pumped midinfrared semiconductor lasers, in which the effects of several design parameters are analyzed. We observe that when the short wavelength waveguide mode overlaps the long wavelength gain region, photon re-absorption occurs, favoring long wavelength emission. We demonstrate high power output from a laser emitting at two wavelength bands.
