Sub-terahertz scanning near-field optical microscope using a quartz tuning fork based probe.
Li X, Sun J, Jin L, Shangguan Y, Chen K, Qin H. Li X, et al. Opt Express. 2023 Jun 5;31(12):19754-19765. doi: 10.1364/OE.487167. Opt Express. 2023. PMID: 37381384 Free article.
We report a sub-terahertz scattering-type scanning near-field microscope (sub-THz s-SNOM) which uses a 6 mm long metallic tip driven by a quartz tuning fork as the near-field probe. Under continuous-wave illumination by a 94 GHz Gunn diode oscillator, terahertz near …
