The properties of a 1.3μm GaInNAs Double Quantum Well (QW) ridge waveguide (RWG) laser have been systematically studied for GaAs based uncooled long wavelength lasers. The threshold current, transparency current, optical gain, internal loss and quantum efficiency characteristics were assessed by light-current (L-I) measurement using devices with different geometries. Measurements of gain spectra versus injection current and temperature were taken and used to analyze GaInNAs as an active material in terms of gain, loss and transparency. The experimental observations are discussed. The results are compared with those obtained from lasers made by other conventional materials. The high characteristic temperature (T0=155K from 20°C to 75°C) and comparable stimulated emission to InP based lasers offer the promise of application as a light source for low cost data communication systems.
