| 20090027683 | INTERFEROMETER, DEMODULATOR, AND SPLITTING ELEMENT - 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. | 01-29-2009 |
| 20090303490 | DELAY INTERFEROMETER - In a delay interferometer, a Michelson delay interferometer unit is mounted on a package made of a Kovar material. The Michelson delay interferometer unit has optical components including a beam splitter which splits an optical signal, reflectors which reflect the split optical signals, and an optical phase adjusting plate which is inserted into an optical path of the optical signal, and which is used for temperature compensation. The delay interferometer includes a glass substrate on which the optical components are bonded and mounted, and an elastic member which is interposed between the delay interferometer unit configured by the optical components mounted on the glass substrate, and a bottom portion of the package. | 12-10-2009 |
| 20090303491 | DELAY INTERFEROMETER - In a delay interferometer in which a Michelson delay interferometer unit is mounted in a package having first and second sidewall portions that are perpendicular to each other, the delay interferometer includes: a Michelson delay interferometer unit in which first interference output light obtained by processing input light that is received through an input port disposed in the first sidewall portion is output through a first output port disposed in the first sidewall portion, and second interference output light is output from a second output port disposed in the second sidewall portion; and a first optical axis shifting member which shifts an optical axis position of the first interference output light in parallel to the first sidewall portion, to cause the light to be supplied into the first output port. | 12-10-2009 |
