토토 후기Phase-stabilized femtosecond frequency comb and optical frequency

Characteristics of electrically-driven single-cell pho토토 커뮤니티 순위nic crystal lasers operating at room temperature are discussed. Modified pho토토 커뮤니티 순위nic crystal structures that enable highly-efficient pho토토 커뮤니티 순위n out-coupling from the wavelength-scale cavity are 토토 커뮤니티 순위 be introduced. The vertical beaming scheme and the all-fiber coupling scheme are discussed in detail, showing the possibility of high optical coupling efficiency in excess of 80%.
