铁电液晶波导中相位匹配二次谐波的产生
True phase-matched second-harmonic generation in a waveguide of crosslinkable ferroelectric liquid crystals is demonstrated. These materials allow the formation of macroscopically polar
structures whose order can be frozen by photopolymerization. Homeotropic alignment was chosen which offers decisive advantages compared to other geometries. All parameters contributing to the
conversion efficiency are maximized by deliberately control领 the supramolecular arrangement.The system has the potential to achieve practical level of performances as a frequency doubler for low power laser-diodes. 组合式多功能椭偏仪
