    A short-wavelength (approximately 0.8mum) GaAs/AlGaAs graded-index separate-confinement heterostructure quantum-well laser has been monolithically integrated with a long-wavelength (approximately 8mum) GaAs/AlGaAs multiple-quantum-well infra-red photodetector on a semi-insulating GaAs substrate by molecular beam epitaxy. The vertical integration method is used and the combined structure is a pinin structure. Both the laser and detector exhibit excellent characteristics. At room temperature, the ridge waveguide laser has an extremely low threshold current of 25 mA and a differential quantum efficiency above 65% with a stripe width of 20mum. The quantum-well detector has a peak response at 8mum and a responsivity of 0.7A/W.

    A two-colour infra-red photodetector using multistacks of GaAs/AlGaAs quantum wells is demonstrated. The response peaks are at 3.9 and 8.1 mum. The peak responsivities of the detector are 0.4A/W and 35mA/W for 8.1mum and 3.9mum bands, respectively. The detectivities of the 3.9 and 8.1 mum bands are 7.5 x 10(9) and 1.5 x 10(10)cmHz1/2/W. These values are the best reported results for two-colour detectors with peak sensitivities in the spectral regions of 3-5 and 8-12mum.
