| Outline of Final Research Achievements |
Research objective is to develop wavelength convertors based on compound semiconductor for vertical cavity surface emitting lasers by introducing a total-reflction waveguide in a cylindrical Bragg-reflection waveguide. We have obtained research achievements by numerical simulation as follow:
1) In GaAs/Air cylindrical waveguide, phase matching condition between total-reflection and Bragg-reflection modes cannot be achieved.
2) In a folded U-shaped waveguide, high-efficiency as well as small foot-print size can be achieved by connecting straight waveguides with half-arc waveguides.
