Organic Crystal Films for Electro-Optic Modulator
Abstract
During the period of performance from August 1st, 1999 to July 31st, 2001 the following was done: KD(*)P and N-(4-nitrophenyl)-(L)-prolinol (NPP) single crystals in longitudinal E-O modulator configuration have been studied. The E-O coefficient for KD(*)P, which is in good agreement with literature data, and electro-optical parameters for NPP were obtained. The latter are much higher that received by other authors, which is explained by a substantial stress in the crystal due to the conversed piezoelectric effect. An E-O thin film modulator integrated with input and output coupling prisms was designed. Successful injection, propagation and decoupling light from the experimental prototype of the modulator were demonstrated. Applicability of different shape prisms for light coupling was explored. An opportunity to grow a thin organic film in a cell comprising a cell itself and a prism used as a lid, similar to the plate-guided method was studied. Mr. Javier Wu defended his thesis 'Nonlinear Optical Properties of Organic Thin Film Materials'. Javier continues his studies in the Ph. D. program of the University of PR. Mr. Zhifu Liu defended his Ph.D. thesis 'Electro-optical effect in single crystal films', and got a position with industry.
