摘　　要：采用X切LiNbO_3基片,设计并研制了分段电极Mach-Zehnder(M-Z)干涉仪光波导宽带微波电场接收器。其中,电极分段数为10段,器件尺寸为60×6×0.5 mm。研究结果表明,当接收光功率信噪比为5 dB时,器件可检测到的最小电场强度小于60 mV/m,并且接收带宽达到10 MHz～3.6 GHz。An integrated optical waveguide E-field receiver at wide-band microwave with segmental electrodes using a proton-exchanged LiNbO3 Mach-Zehnder （M-Z） interferometer has been designed and fabricated. The device consists of ten sections of electrode and its structure size is 60 × 6 ×O. 5 ram. The experimental results show that the minimum detectable electric field is 60 mV/m with the bandwidth of 10 MHz - 3.6 GHz in the receiving condition for optical power, which has a signal-noise ratio of 5 dB.
