Metal-clad ridge-waveguide lasers with stripe widths between 1.5 and 3 μm have been developed in InGaAsP-InP for 1.3 μm wavelength. By an appropriate design for these lasers, threshold currents as low as 20 mA are achieved for 200-μm-long cavities. The corresponding low heat dissipation enables cw operation of upside-down mounted devices up to 85 °C heat sink temperature.
