耦合到低温生长的砷化镓光混频器的谐振槽和偶极天线已经在太赫兹工作频率下制造和测试。与耦合到宽带自互补螺旋天线的混频器相比，从谐振结构可以看出输出功率增强。在谐振频率下可达到高达 300 Ω 的驱动点阻抗。这些器件可用作亚毫米外差接收器的固定频率本地振荡器。
Resonant slot and dipole antennas coupled to low‐temperature‐grown GaAs photomixers have been fabricated and tested at terahertz operating frequencies. Enhanced output power is seen from the resonant structures compared to mixers coupled to broadband self‐complementary spiral antennas. Driving point impedances as high as 300 Ω are attained at the resonant frequencies. These devices will be useful as fixed frequency local oscillators for submillimeter heterodyne receivers.
