Design of Semiconductor Contact Grating Terahertz Source with Enhanced Diffraction Efficiency

We report a semiconductor contact grating terahertz source design based on a rectangular profile for phase-matched terahertz generation in the long infrared pump wavelength range. The calculations show that the best diffraction efficiency can be achieved by a filling factor significantly smaller tha...
