| Outline of Final Research Achievements |
In this research, we attempted to realize two types of nano/micro lasers using peculiar focusing properties of radially polarized beams. Firstly, we investigated the possibility of nano-plasmonic laser which uses clocking effect and electric field enhancement effect of metal nano-structure of focused radially polarized beam. Secondly, we attempted to develop self-subwavelength-focused single-chip lasers by using a radially polarized beam and dielectric material. As a result, we developed new type of photonic-crystal lasers which generate radially polarized beam efficiently. And we showed that the generation of subwavelength localized electric field can obtain by surface processing on the lasers.
