摘要： In a signal regeneration device in which recovery of a signal quality which has been degraded during transmission in optical communication and extension of a transmission distance are achieved, the most representative method of quantizing an optical phase is a phase sensitive amplifier (PSA) and a technique that utilizes an optical parametric process through use of a highly nonlinear optical medium, but there is a demand for a technique of quantizing an optical phase which is not accompanied with an optical parametric gain, has small-sized elements, is easily integrated, and does not require high power pump light. By a technique of a hybrid optical phase squeezer (HOPS), when a phase of input light is quantized to M levels (M>2), phase conjugate light of the input light and (M−1)th phase harmonic light of the input light are subjected to power modulation to be coherently added, so that quantization of the optical phase is performed through use of a simple four-wave mixing (FWM) that is not accompanied with the optical parametric gain and a general optical amplifier by using a general nonlinear optical medium such as silicon, and accordingly, a GER of equal to or higher than 30 dB can be obtained, even if a nonlinear optical element having a low nonlinearity is used.

摘要： A thermal nonlinear cell and method. The cell includes a substantially planar nonlinear medium and a mechanism for removing thermal energy from the medium in a direction substantially orthogonal to said medium. In one embodiment, the mechanism for removing thermal energy is a thermally conductive window mounted adjacent to the medium. Preferably, the mechanism includes plural thermally conductive windows between which the nonlinear medium is disposed. In the best mode, the windows are sapphire and the nonlinear medium is a fluid. The windows and the medium are transmissive with respect to first and second beams that interfere with each other and create an interference pattern in the cell. The interference pattern is sampled by a sampling hologram created within the multiple layers of the medium. The interference pattern is used via a sampling hologram to create a phase conjugate of a signal beam. The windows move thermal energy from the medium in a direction transverse to the longitudinal axis of the medium. This energy is then removed by heat sinks disposed at the ends of the stack of windows. In an alternative embodiment, the mechanism for removing thermal energy includes first and second mirrors mounted adjacent to the medium in a substantially parallel face-to-face relation. Preferably, the mirrors are heat exchangers such as slot-jet impingement coolers. In this embodiment, a transparent window is disposed between the mirrors and the nonlinear medium is disposed between the mirrors and the window. The mirrors are adapted to reflect first and second beams into the medium where they interfere to provide the interference pattern needed to create a phase conjugate beam.

摘要： An optical phase conjugator includes an optical nonlinear medium for receiving original signal light and pumping light, and generating and outputting phase-conjugate light by a nonlinear optical effect. The optical nonlinear medium contains an element which can be activated upon irradiation of activation light and has an amplification function with respect to at least the pumping light. The optical phase conjugator comprises a first optical coupler for coupling the original signal light and the pumping light and then inputting the coupled light into the medium, and a second optical coupler for inputting the activation light into the medium. An improvement in phase-conjugate light generating efficiency is attained, and phase-conjugate light having a sufficiently high intensity can be obtained by the optical phase conjugator with a simple, compact arrangement.

摘要： The present invention provides an apparatus and method for performing polarization-insensitive four-photon mixing of optical signals. The polarization-insensitive optical mixer includes a polarization splitter for splitting an optical signal into parallel and perpendicular polarization components, different mixing paths for mixing a pump signal of like polarization with each of the parallel and perpendicular components in a nonlinear mixing device, and a polarization combiner for combining the resulting mixing products. Certain of the mixing products represent phase conjugates of the input optical signal, and are therefore useful in compensating for chromatic distortion in optical fiber.

摘要： Four-wave mixing is used to produce a steered optical phase conjugate wave. First and second pump waves are combined with a probe wave in a nonlinear medium within an optical conjugate, producing an optical phase conjugate wave. The magnitude of the wave vectors corresponding to the first and second pump waves are different, causing the optical phase conjugate wave to define a non-zero angle .theta..sub.0 relative to the probe wave. In a first embodiment, the wavelengths of the first and second pump waves are controlled to vary the angle, while in a second embodiment, the intensities of the two pump waves are modified.

摘要： An optical input beam is transmitted through a non-linear medium capable of two-wave mixing gain by photorefractive, Brillouin, Raman, or other non-linear optical mechanism. A psuedo-conjugator retroreflects the input beam which has passed through the medium, back into the medium. The retroreflected beam acts as a seed, which lowers the threshold for producing a self-pumped conjugate reflected beam in the medium by stimulated scattering. The pseudo-conjugator may be a flat array of retroreflecting elements in the form of spheres or corner reflectors. A mosaic pattern of conjugating elements can be phase-locked to yield larger apertures and/or energy scaling, in a master-oscillator, power-amplifier (MOPA), or a four-wave mixer (FWM) configuration. The retroreflected beam can be modulated to temporally encode information onto the conjugate beam, and/or polarized to increase the system efficiency. The input and self-pumped conjugate reflected beams can be used as reference or pump beams in a FWM configuration.
