报道了基于静磁前向体波（MSFVW）的导波磁光（MO）布拉格盒的实现及其在通信和信号处理中的应用。本文分析了非共线共面几何结构中，导光波从MSFVW中的布拉格衍射。微带线换能器的设计，促进宽带MO布拉格衍射与电子可调谐的微波载波频率（2.0至12.0 GHz）的简要讨论。实验结果与纯和铋掺杂的钇铁石榴石（YIG）波导中得到的布拉格细胞和理论预测的比较。详细介绍了布拉格盒在光束调制、扫描/开关和射频光谱分析等方面的应用。>
Realization of magnetostatic forward volume wave (MSFVW)-based guided-wave magneto-optic (MO) Bragg cells and their applications to communications and signal processing are reported. Bragg diffraction of guided-optical waves from the MSFVW in a noncollinear coplanar geometry is analyzed. The design of microstrip line transducers that facilitate wideband MO Bragg diffraction with electronically tunable microwave carrier frequencies (2.0 to 12.0 GHz) are briefly discussed. Experimental results obtained with the resulting Bragg cells in both pure and bismuth-doped yttrium-iron-garnet (YIG) waveguides and a comparison to the theoretical predictions are presented. Applications of the Bragg cells to light beam modulation, scanning/switching, and RF spectral analysis are presented in detail. >
