| Outline of Final Research Achievements |
We investigated the generation mechanism of high quality (Q) factor in a metal-embedded semiconductor pillar cavity. The properties of the cavity including its Q factor were revealed by numerical and alalytical calculations. We fabricated the metal-embedded cavity by electron beam lithography and dry etching techniques. The Q factor of the cavity was probed by DA pair emission of n-GaAs and evaluated. Gammadion type chirality was introduced into the cavity. The Q factor and radiation field of the cavity mode were investigated by numerical calculation.
