Temperature Controlled Interferometer For Phase Demodulation |
摘要 |
An interferometer includes an optical beam splitter that splits an input optical signal into a first optical signal propagating in a first optical path comprising free space and a second optical signal propagating in a second optical path comprising a dielectric medium. A differential delay delays the second optical signal relative to the first optical signal by a differential delay time that is proportional to at least one of a temperature and a refractive index of the dielectric medium. A temperature controller in thermal contact with the dielectric medium changes the temperature of the dielectric medium to control at least one of thermal expansion/contraction and a temperature dependent change in the refractive index of the dielectric medium, thereby changing the differential phase delay. An optical beam splitter/combiner optically coupled to the first and second optical paths generates a first and second interferometric optical signal having an amplitude and phase that is related to the differential delay.
