Abstract :
An investigation of the properties of discrete and integrated InP-based strained InxGa1-xAs-InP (0.33⩽x ⩽0.73) quantum-well lasers both theoretically and experimentally, taking into account the effects of Auger recombination, is discussed. The variation of threshold current, differential quantum efficiency, and small- and large-signal modulation properties of broad-area and ridge lasers have been determined. In determining the modulation behavior, the extrinsic time constant limitations of compressive- and tensile-strained lasers have also been characterized. The modulation properties of quantum well electroabsorption modulators integrated monolithically with the lasers have also been characterized
