  • Abstract
    The record quantum efficiency operation of 680 nm GaInP/AlGaInP singlemode lasers is reported. A low threshold current of 40 mA and a very high quantum efficiency of 46% per facet were measured for a 5×500 μm2 as-cleaved ridge waveguide laser. For the AR/HR coated devices a quantum efficiency as high as 92% was achieved
