We investigate thermal tuning of an ultra-high quality (Q) terahertz (THz) whispering-gallery mode resonator (WGMR) made of low loss silicon. The Si THz WGMR can be continuously tuned with a rate of about 29 MHz/K in the frequency range from 650 GHz to 666 GHz. Furthermore, we utilize the Si WGMR to extract the thermo-optic coefficient of Si at 459 GHz and 659 GHz in the temperature range from 295 K to 363 K.We investigate thermal tuning of an ultra-high quality (Q) terahertz (THz) whispering-gallery mode resonator (WGMR) made of low loss silicon.

硅太赫兹回音壁模式谐振器的热调谐

我们研究了由低损耗硅制成的超高品质 (Q) 太赫兹 (THz) 回音壁模式谐振器 (WGMR) 的热调谐。Si THz WGMR 可以在 650 GHz 至 666 GHz 的频率范围内以大约 29 MHz/K 的速率连续调谐。此外,我们利用 Si WGMR 在 295 K 至 363 K 的温度范围内提取 459 GHz 和 659 GHz 下 Si 的热光系数。 我们研究了超高品质 (Q) 太赫兹 (THz) 的热调谐回音壁模式谐振器 (WGMR) 由低损耗硅制成。Si THz WGMR 可以在 650 GHz 至 666 GHz 的频率范围内以大约 29 MHz/K 的速率连续调谐。此外,我们利用 Si WGMR 在 295 K 到 363 K 的温度范围内提取 Si 在 459 GHz 和 659 GHz 的热光系数。
