| Abstract |
In order to suppress lasing oscillation and obtain high light power, We have proposed a novel SLD which is formed with a straight and tilted waveguide. The window region is used to suppress lasing oscillation and reduce the facet reflectivity. High power and low reflectivity is obtained by the straight and tilted waveguide. Based on the theoretical analysis, we have fabricated the SLD with the waveguide of 500 μm length and window region of 50 μm by LPE equipment. Through the measurements of optical characteristics, the output light power of 3 mW was obtained at the 150 mA CW injection current and 25^{circ}C. We have confirmed that the proposed SLD has a 0.8 dB spectrum ripple lower than 1 dB which is sufficiently low reflectivity for preventing lasing. |
