A detailed operating characteristics of InGaAsP/GaAs separate confinement heterostructure (SCH) single-quantum-well (SQW) wide-stripe lasers emitting at 808 nm grown by liquid phase epitaxy (LPE) is reported. The temperature dependences of the lasing wavelength λ, the threshold current density Jth and differential quantum efficiency ηd are studied The effects of the cavity length L on the threshold current density Jth and the differential quantum efficiency ηd are studied The threshold current density Jth increases with increasing temperature T. But the increase of Jth with temperature T is slightly deviated form the exponential dependence. The data fitting of Jth with between 10 °C and 40 °C demonstrates a record characteristic temperature To of 218K, indicating a minor influence of temperature on Jth.
