Developments in Photorefractive Two-beam Coupling Systems
Date_______________________ The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards fo scholarly work in the above mentioned discipline. Photorefractive systems hold the promise for improving the performance of photonic signal processing applications. This thesis describes several developments pert...
متن کاملManipulating the information carried by an optical beam with reflexive photorefractive beam coupling
A two-beam coupling interaction of an information-bearing beam with a copy of itself in a photorefractive medium changes the spatiotemporal nature of the beam. We analyze the reflexive coupling of an informationbearing beam carrying two or more spatiotemporal signals, using a one-dimensional model. We find that the statistical information content of the beam can be increased or decreased by use...
متن کامل−70 dB optical carrier suppression by two-beam coupling in photorefractive media
Suppression of an optical carrier from an RF modulated laser beam of wavelength 532 nm is performed using two-beam coupling in photorefractive barium titanate. A theoretical analysis reveals that perfect suppression can be achieved at a specific modulation strength, which depends on the gain and intensity ratio between the two beams. The experiments achieve a maximum of −72.9±2.4 dB carrier sup...
متن کاملBeam coupling and locking of lasers using photorefractive four-wave mixing.
We discuss the use of photorefractive four-wave mixing for coupling and locking of lasers. A demonstration of the double phase-conjugate mirror and the semilinear passive phase-conjugate mirror, pumped simultaneously by different lasers, is described. Cleanup of a distorted laser beam using another local laser and configurations for the phase locking of lasers are discussed.
متن کاملInfluence of alternating field frequency on enhanced photorefractive gain in two-beam coupling.
We derive an analytic expression describing the intensity and field frequency dependence of photorefractive gain in two-beam coupling under an alternating square-wave electric field. We determine the frequency and intensity ranges over which the gain is maximum and time independent. Experimental results for Bi(12)GeO(20) crystals are presented.
