Abstract (in Japanese) (See Japanese page) 
(in English) We demonstrate a first-order interference between coherent light at 1580~nm and 795~nm by using a frequency-domain Mach-Zehnder interferometer~(MZI) composed of two partial frequency converters as a frequency-domain BS. The BSs are realised by a second-order nonlinear optical effect in a periodically-poled lithium niobate waveguide with a strong pump light. The observed visibility is over 0.99 at 50% conversion efficiencies of the BSs. Toward photonic quantum information processing, sufficiently small background noise photon rate is necessary. From measurement results with a superconducting single photon detector~(SSPD), we discuss the feasibility of the frequency-domain MZI in a quantum regime. Our estimation shows that the single photon interference with the visibility above 0.9 is feasible with practical settings.
