The purpose of this study is to develop high speed time-space electro-optic modulators by use of simple domain-engineering processes in an electro-optic crystal. The shape of the domain inverted region in a traveling-wave electro-optic phase modulator is theoretically designed in consideration of velocity mismatch between an optical group velocity and a microwave phase velocity in a crystal for designed spatial distribution of the modulation index/modulation phase within an optical beam cross section.We have developed five new devices or functions ;1. Ultrafast traveling-wave electro-optic deflector and it application to ultra short optical pulse generation,2. All optical streak camera,3. Sub-picosecond optical pulse generation with repetition rate of several tens of gigahertz using electro-optic standing-wave phase grating,4. Inversion of the time axis of optical beam based on ultrafast deflection,5. Electrooptic transparent frequency conversion of a continuous-lightwave based on multistage phase modulation.

本研究的目的是在电光晶体中利用简单的域工程工艺来研制高速时空电光调制器。本文从理论上设计了行波电光相位调制器中畴反转区的形状，并考虑了晶体中光群速度与微波相速度之间的速度失配，从而设计了光束截面内调制指数/调制相位的空间分布。超快行波电光偏转器及其在超短光脉冲产生中的应用;全光学条纹相机，3.利用电光驻波相位光栅产生重复频率为几十GHz的亚皮秒光脉冲。基于超快偏转的光束时间轴反演，5.基于多级相位调制的连续光波电光透明频率变换。
