CW Operation of 0.67 µm GaInAsP/AlGaAs Laser at 208 K Grown on GaAs Substrates by LPE

説明

<jats:p> CW operation of GaInAsP/AlGaAs oxide stripe lasers with the stripe width of 8 µm was achieved at the heat-sink temperature of 208 K. The maximum light emission power and differential quantum efficiency obtained at room temperature pulse condition were 30 mW/facet and 46%, respectively. The characteristic temperature of threshold <jats:italic>T</jats:italic> <jats:sub>0</jats:sub> observed at the CW condition was 93 K at the tempeature of 113–200 K. </jats:p>
