Abstract:A four‐wavelength DBR laser array, fabricated using selective metalorganic vapor‐phase epitaxy (MOCVD) growth, has been developed as a light source for a wavelength division multiplexing (WDM) system. Four different lasing wavelengths were obtained by varying the thickness of the waveguide. This enabled fabrication of lasers having different wavelengths but gratings with the same pitch.
First, the InGaAsP layer grown on an InP substrate which was patterned with stripes of different widths by using an SiO2 mask… Show more
