Abstract :
We developed integrated multiwavelength lasers with waveguide couplers using a novel selective metalorganic vapor-phase epitaxy (MOVPE) technique. The lasing wavelength was controlled by modulating the effective refractive index of distributed Bragg reflector (DBR) waveguides. Array lasing wavelengths were distributed from 1548.0 to 1553.5 nm with an average spacing of 1.8 nm. Output power exceeding 100 μW was obtained for each DBR laser. The propagation loss of the waveguide coupler was about 16 dB for inner ports and 20 dB for outer ports with a 6-dB splitting loss
