Noncollinear parametric fluorescence by chirped quasi-phase matching for monocycle temporal entanglement
Akira Tanaka, Ryo Okamoto, Hwan Hong Lim +9
Quantum entanglement of two photons created by spontaneous parametric downconversion (SPDC) can be used to probe quantum optical phenomena during a single cycle of light. Harris [P…
Coupling of ultrathin tapered fibers with high-Q microsphere resonators at cryogenic temperatures and observation of phase-shift transition from undercoupling to overcoupling
Masazumi Fujiwara, Tetsuya Noda, Akira Tanaka +3
We cooled ultrathin tapered fibers to cryogenic temperatures and controllably coupled them with high-Q microsphere resonators at a wavelength close to the optical transition of dia…
Generation of broadband spontaneous parametric fluorescence using multiple bulk nonlinear crystals
Masayuki Okano, Ryo Okamoto, Akira Tanaka +2
We propose a novel method for generating broadband spontaneous parametric fluorescence by using a set of bulk nonlinear crystals (NLCs). We also demonstrate this scheme experimenta…
