1Subwavelength thick ultrahigh-Q terahertz disc microresonators显示文摘Artificial structures that exhibit narrow resonance features are key to a myriad of scientific advances and technologies.In particular,exploration of the terahertz(THz)spectrum—the final frontier of the electromagnetic spectrum—would greatly benefit from high-quality resonant structures.Here we present a new paradigm of terahertz silicon disc microresonators with subwavelength thickness.Experimental results utilizing continuouswave THz spectroscopy establish quality factors in excess of 120,000 at 0.6 THz.Reduction of the disc thickness to a fraction of the wavelength reduces the losses from the silicon substrate and paves the way to unparalleled possibilities for light–matter interaction in the THz frequency range.Dominik Walter Vogt Angus Harvey Jones Thomas Alan Haase Rainer Leonhardt 2020Photonics Research2020,8,7:0
