摘要: We report a traveling-wave electro-optic sinusoidal deflector which operates in picosecond time scale. The is fabricated by use of simple domain-engineering processes LiTaO3 crystal. shape the domain inverted region phase modulator theoretically designed consideration velocity mismatch between an optical group and microwave crystal for spatial linear distribution modulation index within beam cross section. At deflection period 61.5 ps, maximum resolvable spot number 13.0±0.6 demonstrated. Our EOD can be applicable to time-space information processing systems with minimum temporal resolution 1.5 ps.
