A comprehensive design method for long wavelength strained quantum-well lasers is applied to design uncooled multiple-quantum-well AlGaInAs-InP 1.3-μm lasers for communication systems. The method includes multiband effective mass theory and electromagnetic waveguide theory. The resulting AlGaInAs-InP laser has a threshold current of 12.5 mA at 25°C, with a slope efficiency of 0.43 W/A, at 77 K or greater characteristic temperature, a 38° perpendicular far-field beam divergence, and will operate at temperatures in excess of 100°C
