摘　　要：介绍了光学生成毫米波技术研究的背景及意义。综述了几种主流的毫米波光学产生技术,主要包括直接调制法、外部调制法、光外差法,以及在此基础上的改进方法:如改进的双边带调制产生光毫米波方案,新型双均匀光栅结构产生毫米波的方法等。并介绍了2种新型光学生成毫米波方法,包括采用光纤光栅滤波器获得具有一定间隔双波长成分的光脉冲光谱实现毫米波副载波光信号产生的方法以及光学倍乘法。The background and significance of the research on optical generation technology of millime ter-wave are introduced. Several mainstream optical generation technologies of millimeter-wave are reviewed, ineluding direct-modulation, external-modulation and optical heterodyne; the improved methods are also summarized, including a novel scheme for optical millimeter-wave generation based on double-sideband modulation, and a new double-uniform fiber grating millimeter-wave generator and so on. In addition, two novel optical generation technologies of millimeter-wave are reviewed, including a method to realize millimeter-wave subcarrier optical signal generation by using a double wavelength optical spectrum of a certain distance with fiber grating filter and optical frequency multiplication.
