Bismuth-substituted yttrium iron garnet (Bi:YIG) films were prepared by using spin coating processes with metal-organic-decomposition-method-based solutions on crystalline silicon (Si) substrates, and their magneto-optic properties at the 1550-nm wav

We introduce a thick integrated polarization beam splitter (PBS) based on a bridged directional coupler (DC) with three planar waveguides of 400-nm-high silicon core layer. Contrary to the conventional thin DC-type PBSs using the cross coupling effec

We have investigated the ultimate limits of nonuniform grating couplers (NGCs) for optimized fiber coupling to silicon waveguides, compared to uniform grating couplers (UGCs). Simple grating coupler schemes, which can be fabricated in etching steps o

We demonstrate improved single photon detection efficiencies of InGaAs/InP avalanche photodiodes (APDs) in a wavelength-division-multiplexed (WDM) scheme for high-capacity plug-and-play-type two-way quantum key distributions (QKDs). Single-photon det

We have measured the magneto-optic (MO) properties of film-type bismuth substituted yttrium iron garnets (Bi1.5:YIG, Bi1.5Y1.5Fe5O12) prepared by using metal-organic-decomposition (MOD) method on glass substrates at the 1310-nm and 1550-nm wavelength

We propose a wavelength-division-multiplexed (WDM) scheme for high-speed and high-capacity quantum communications in a single transmission fiber. The scheme involves multiple weak coherent-state signal pulse sources (WCS-SPSs) and multiple single pho
