    摘要： An interferometer of the invention includes: a first splitting element which includes a first transparent medium and a first splitting film formed on the first transparent medium, and which splits incident light into a first split beam and a second split beam, the first split beam being the incident light reflected by the first splitting element and the second split beam being the incident light transmitted through the first splitting element; and a second splitting element which includes a second transparent medium and a second splitting film formed on the second transparent medium, and which causes interference between the first split beam and the second split beam passed through different optical paths, the second splitting element being positioned such that a positional relationship between the second transparent medium and the second splitting film with respect to a direction of incidence on the second splitting element of the first split beam is opposite to a positional relationship between the first transparent medium and the first splitting film with respect to a direction of incidence of the incident light on the first splitting element.

    摘要： A demodulator includes: a Michelson interferometer having: a half-mirror which splits an optical signal, emits a first split light to a first optical path, and emits a second split light to a second optical path; a first reflector which reflects the first split light to the half-mirror; and a second reflector which reflects the second split light to the half-mirror, wherein the half-mirror recombines the first split light and the second split light, and emits a recombined optical signal while splitting the recombined optical signal; and an balanced optical detector which receives the recombined optical signals from the Michelson interferometer, and generates a demodulated signal based on the two recombined optical signals. The length difference between the first optical path and the second optical path is set so that the second split light has a delay time equal to a one-bit period, with respect to the first split light.
