已经开发出工作频率为 200-500 GHz 的高输出功率光电混频器模块。该模块由单行进载流子光电二极管、PD波导模式转换耦合器和带有输出亚太赫兹波的矩形波导的紧凑金属封装组成。所制造的模块具有约 300 GHz 的 10 dB 下带宽和在 350 GHz 时高达 -2.7 dBm 的输出功率。这是迄今为止报告的在 350 GHz 频段运行的光电混频器模块的最高值。
A high-output-power photomixer module operating at 200-500 GHz has been developed. The module consists of a uni-traveling-carrier photodiode, a PD-waveguide mode-conversion coupler, and a compact metal package with a rectangular-waveguide that outputs sub-terahertz wave. The fabricated module exhibits a 10- dB down bandwidth of about 300 GHz and an output power as high as -2.7 dBm at 350 GHz. This is the highest value ever reported for a photomixer module operating at 350-GHz band.
