A high speed 1053nm superluminescent diode (SLD) with ridge-waveguide structure has been fabricated. By optimizing of the growth parameters such as temperature, growth rate, epitaxial materials with excellent crystal quality were attained. The photoelectric characteristics of the SLD depended on temperature and driver current were analyzed. The coefficient of the wavelength shift with temperature was 0.35nm/℃.The wavelength of the SLD shift with driver current insensitive to the temperature. A -3dB cutoff frequency of 1.7GHz was obtained at a DC bias current of 100mA and 25℃,corresponding to 2.5mW output power from single mode fiber (SMF) with spectral modulation of less than 0.15dB and spectral width of 24nm.
