Nature of the interference pattern produced on reflection at a phase-conjugate mirror

Abstract

We show theoretically and experimentally that the positions of the fringes produced by interference between a wave incident upon a phase-conjugate mirror and the wave leaving the mirror depend on the phase associated with the incident wave. This result is in contrast to that obtained when an ordinary metal mirror is used, in which case the interference pattern is found to beindependent of the phase of the incident wave.

Interferometry with Phase Conjugate Mirrors and Measure of One-Way Velocity of Light

“…Mandel, Wolf, and co-authors (3) confirmed these predictions with an experiment in which a laser beam was sent in the interferometer and a phase shifter was introduced in different positions in order to vary the phase of the incident and pumping waves. This experiment proves that the Michelson interferometer with a PCM is able to verify, at least in the case of impinging coherent light, the interference between a linearly polarized impinging wave and its conjugate wave.…”

“…The interference produced on reflection at phase-conjugate mirror has been studied in detail both from a classical and quantum point of view theoretically, even if only the classical aspects of this object have been experimentally tested. (2)(3)(4) The use of this interferometer was proposed in order to study the intrinsic non-locality of quantum mechanics. (5) In this paper we will show that this apparatus is able, at least in principle, to measure the one-way velocity of light and therefore to solve the problem of its conventionality.…”

Phase Conjugate Mirrors, One Way Velocity of Light and Measure of Anti-Coherence

“…[2][3][4] If a linearly polarized light beam (for example, in the x-direction) impinges into the IPCM, the splitting of the beam by the beamsplitter BS and the reflection of the produced beams on the metallic and phase-conjugate mirrors do not produce any variation of the polarization. So, when the two beams overlap at the beamsplitter, an interference effect will occur with an oscillation of the amplitude which is a function of the optical parameters of the apparatus and of the beam.…”

Phase-conjugate distance measurement interferometer with frequency modulation of a laser diode

“…An SPPCM in an interferometer can cancel out any nonuniform phase distortions, while a phase conjugator cannot eliminate a spatially uniform phase change of an incident beam. 4,5 A heterodyne interferometer would be realized by means of frequency-modulated continuous wave (FMCW) techniques by modulating the phase of the conjugate wave with a tunable LD. 6,7 In this paper, a wavefront-matched interferometer 8 with an external-cavity laser diode (EC-LD) is presented with two BaTiO 3 SPPCMs instead of two ordinary mirrors.…”
