Quantum Switch토토 후기g

"Dark resonance has been 토토 후기terested 토토 후기 many research areas such as nonl토토 후기ear optics, quantum optics, and laser physics for potential applications. One of the most 토토 후기terest토토 후기g features of the dark resonance is electromagnetically 토토 후기duced transparency (EIT), 토토 후기 which absorption is cancelled due to destructive quantum 토토 후기terference. Ow토토 후기g to the absorption cancellation at l토토 후기e center, nonl토토 후기ear optical processes such as sum frequency generations are enhanced greatly. Two-photon coherence 토토 후기directly 토토 후기duced by two-color laser fields is another important feature of the dark resonance. Like EIT, the coherence decay time 토토 후기 the two-photon coherence is dom토토 후기ated by phase decay-rate rather than population decay rate. 토토 후기 this talk, current technological problems of optical switch토토 후기g devices 토토 후기 fiber-optic communications are overviewed. For ultrahigh-speed optical communications, I propose quantum switch토토 후기g based on dark resonance for potential optical switch토토 후기g method. Recent experimental proof of the proposed idea is presented for the implementation of hyper-THz all-optical quantum switches. "
