Abstract-Mode identification for ultra high-Q terahertz whispering-gallery modes
We report on the identification of terahertz whispering-gallery modes (WGMs) using the phase information from coherent continuous-wave (CW) spectroscopy. The demonstrated WGM has an ultra high quality (Q) factor of 1.5 × 104 at 0.62 THz.
