The invention provides a terahertz wave emitter, which mainly comprises a microcavity laser, a semiconductor optical amplifier and a photodiode mixer. Three parts of terahertz wave transmitters with different configurations are formed by integration or partial integration. The externally modulated signal can be input into the THz wave emitter by modulating the microcavity laser current, the semiconductor optical amplifier current, or the photodiode bias voltage. 本发明提供了种太赫兹波发射器，该发射器主要包括微腔激光器、半导体光放大器和光电二极管混频器。三部分通过集成或部分集成形成不同结构的太赫兹波发射器。外部调制信号可以通过调制微腔激光器电流、半导体光放大器电流或光电二极管偏置电压输入太赫兹波发射器。
