太赫兹辐射光整流效应电光效应 ZnTe单晶〈331〉晶向 THz emitter Optical rectification Electro-optic sampling ZnTe 〈331〉-oriented

摘要

根据光整流效应辐射太赫兹理论，计算了〈331〉晶向ZnTe单晶的太赫兹辐射性能.通过与〈110〉、〈111〉晶向对比，当晶体方位角为0°或180°时，利用〈331〉晶向ZnTe单晶辐射太赫兹信号可以与〈111〉晶向相当，强于〈110〉晶向.利用电光取样原理，计算了〈331〉晶向ZnTe单晶的太赫兹探测性能，通过理论计算为〈331〉晶向ZnTe 晶体有效辐射太赫兹波提供理论依据.

Abstract

The THz pulses generation of 〈331〉-oriented ZnTe as emitter via its optical rectification were reported. Compared with 〈110〉、〈111〉-oriented ZnTe crystal, the 〈331〉-oriented ZnTe could even emit THz pulse. When the crystal oriented angle was 00 or 1800, the THz pulse amplitude from 〈331〉-oriented could be equal to 〈111〉-oriented, higher than 〈110〉-oriented. The THz pulses detection performance of 〈331〉-oriented ZnTe as detector was calculated via the electro-optical effect. The theoretical calculation from 〈331〉 ZnTe emitter demonstrated a direct way to optimize the working efficiency of a terahertz emitter.
