| Outline of Final Research Achievements |
Cavities for circularly polarized light with a high quality was designed by numerical calculations for semiconductor-based three-dimensional chiral photonic crystals which are able to control circularly polarized light. Based on this design, a three-dimensional chiral woodpile structure was fabricated by semiconductor nano-fabrication methods including a micro-manipulation technique. For this sample containing quantum dots, micro-photoluminescence measurements at low temperature revealed a cavity mode for circularly polarized light and indicated the Purcell effect between a circularly polarized photon and an exciton in a quantum dot. Though additional accurate measurements are required for the single photon detection, this result suggests the control of a single spin through a circularly polarized photon in the cavity.
