INTERFEROMETER CONFIGURED FOR SIGNAL PROCESSING IN AN INTERFERENCE PATH

摘要

An interferometer is provided that includes a first path and a second path. The first path is configured to propagate an electro-magnetic signal at a first wavelength. The second path is configured to convert a portion of the electro-magnetic signal from the first wavelength to a second wavelength for processing and is configured to convert the portion of the electro-magnetic signal from the second wavelength back to the first wavelength for interference with the electro-magnetic signal of the first path. The first wavelength may be an optical wavelength or any other suitable wavelength of the electro-magnetic spectrum. The second wavelength, which is different than the first wavelength, also may be any suitable wavelength of the electro-magnetic spectrum.

1. An interferometer, comprising:
a first path configured to propagate an electro-magnetic signal at a first wavelength; and an interference path configured to convert a portion of the electro-magnetic signal from the first wavelength to a second wavelength, to convert the portion of the electro-magnetic signal from the second wavelength back to the first wavelength, to interfere the electro-magnetic signal of the first path with the portion of the electro-magnetic signal converted back to the first wavelength, and to modulate a pilot signal onto a signal generated within the interference path.
