Abstract

A novel, low loss and tunable source of continuous terahertz (THz) wave radiation based on frequency conversion in GaAs is presented. The tunability of the device can be achieved by varying the distance between quartz slabs (air gap distance). The output THz power at 1.3 THz for different air gap distances and various waveguide widths has been calculated. By tuning the air gap distance in the range of 290 to 320 nm for a device with 4 cm long at 1.3 THz, a relatively high output power of 3 to 9.5 µW is predicted.
