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…
Phase shift spectra of a fiber-microsphere system at the single photon level
Akira Tanaka, Takeshi Asai, Kiyota Toubaru +4
We succeeded in measuring phase shift spectra of a microsphere cavity coupled with a tapered fiber using a weak coherent probe light at the single photon level. We utilized a taper…
