摘要

The uni-traveling-carrier photodiode (UTC-PD) is a novel PD that uses only electrons as the active carriers. This unique feature is the key for generating continuous millimeter- and sub-millimeter waves up to the terahertz (THz) range. A compact UTC-PD module with a rectangular waveguide output port developed for operation in the F-band exhibits output powers at up to 813 GHz when used in the overmoded condition. A scaled-down rectangular waveguide output UTC-PD module for use in the J-band (220 - 325 GHz) is effective for increasing the output power at higher frequencies. A quasi-optical configuration integrating a UTC-PD and a planar antenna provides operation at higher frequencies. A device integrating a wideband log-periodic antenna exhibits a maximum output-power of 2.6 xW at 1.04 THz with good linearity. A module with a quasi-optical output port operates at frequencies of up to 1.5 THz. Devices integrating resonant narrowband dipole antennas have also been fabricated to further increase the output power. A device having a peak at 1.04 THz exhibits a maximum detected output power of 10.9 μW at 1.04 THz.
