Low loss dielectric ridge waveguide based on high resistivity silicon for E11y Mode Propagation at 750–1000GHz

Abstract

In this paper, dielectric ribbon waveguides (DRWs) are designed to work at 750-1000 GHz. In this frequency band, the Deep Reactive Ion Etching (DRIE) of high resistivity silicon fabrication process is selected to fabricate the DRW. Our experiments show that the average attenuation constant of DRW is merely 0.107dB/mm at 750-1000GHz. Good agreements between the measured and simulated results are observed.
