 note = {We have developed an efficient contact grating device for generating terahertz waves. This device has a very high diffraction efficiency and a wide spectral width. The device has a bi-angular filter and a Fabry-Perot-type structure, which are composed of dielectric multilayers. The bi-angular filter is designed to reflect the 0th-order wave and transmit the -1st-order diffraction wave. Numerical calculations indicate that the new device has a maximum diffraction efficiency over 99% and a spectral width of approximately 20 nm. We measured a high efficiency of 90% over a broad spectral range using a fabricated device., 43rd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz2018)},
