Studies of Optical Wave Mixing and Phase Conjugation
Abstract
The main objective of this research is to carry out theoretical and experimental investigation on optical wave mixing and phase conjugation in various nonlinear media, including photorefractive crystals and optical fibers, as well as novel applications using these nonlinear optical effects. During the research period, we have carried out intensive theoretical and experimental investigation in several important areas in wave mixing and phase conjugation, including the problem of multigrating effects in MPPC, fanning noise reduction by using partially coherent beams, grating enhancement and restoration in photorefractive media, fidelity of image restoration in multimode fibers, reflection-based phase conjugators, cross-talk noise in volume holographic storage, optical phase conjugation and pulse restoration in single mode fibers, photorefractive spatial mode converter for multimode-to-single-mode fiber-optic coupling, energy coupling by partially degenerate four-wave mixing in multichannel lightwave systems, form birefringence of layered media and volume gratings, the effect of beam coherence on mutually pumped phase conjugators (MPPC), polarization-dependent mechanism transformation during self-pumped phase conjugation in Ce:BaTiO3, intensity-dependent absorption and photorefractive properties of some new crystals, including Rb:KNbO3, and Ce:BaTiO3.
