摘要
提出了一种光载毫米波产生新方案,采用双平行马赫曾德调制器(DPMZM),基于线性的光相干技术,产生四倍频的毫米波信号。该技术不需要复杂的电信号处理,以及射频信号的锁相技术,便可产生稳定的毫米波信号。该方法产生的毫米波信号具有频率稳定、抖动小、信噪比高等优点,可以广泛应用于光电器件测试与校准。
A new scheme for photonic generation of millimeter-wave signal（MMW） is presented, which generates frequency- quadrupled MMW based on optical coherent technology using an integrated dual-parallel Mach-Zehnder modulator （DPMZM）. The complicated signal process and phase-locked-loop technology are not necessary. What is more, this method has the advantages of stable frequency, low jitter and high signal to noise ratio（SNR）, which can be widely used to calibrate the O/E converter.
