Abstract (in Japanese) (See Japanese page) 
(in English) Metal-clad wavelength-scale cavities have been expected for application to ultra-small light sources in on-chip optical interconnects due to their strong optical confinement, high thermal conductivity, and low contact resistance. While several types of metal-clad structures have been demonstrated experimentally, optimization of cavity topology has not been explored over the vast parameter space to our knowledge. In this work, we implement iterative computational optimization based on simulated annealing method to optimize the 2D shape of a metal-clad cavity. As a result, we demonstrate a significant improvement in Q factor in the optimized structure from the conventional structures.
