Abstract

We develop and investigate InGaAs/GaAs/InGaP-based heterolasers with asymmetrically grown quantum wells of two types which are capable of dual-wavelength operation and second-harmonic generation at room temperature over a wide range of injection currents: from 0.2 A in CW mode up to 10 A in injection with 200-ns-long pulses. Previously unknown special features of such a dual-wavelength generation are experimentally revealed and interpreted in terms of the competition and coexistence of short- and long-wavelength TE modes, including the "whispering-gallery" modes.
