| Abstract(in English) | A GaInAs/InP MQW-based wavelength demultiplexer composed of a waveguide array in which refractive index varies across the array yielded successful results. Since optical path length differences between waveguides in the array are achieved through refractive-index differences controlled by SiO2 mask design in selective metal-organic vapor phase epitaxy MOVPE, straight waveguide grating is possible with reducing optical propagation losses. A straight waveguide array device with a 1.4 % refractive-index difference was fabricated. The fabrication of a preliminary wavelength demultiplexer was also achieved, obtaining a wavelength separation with around 25-nm spacing and FSR of approximately 100 nm. Moreover, an optical deflector was investigated and achieved primitive deflection at 1460- and 1490-nm incident wavelengths. |
