Near Field Analysis of Individual High Quality Factor THz Resonators
Hale, LL; Lu, Y; Zaman, AM; Addamane, S; Brener, I; Mitrofanov, O; Degl'innocenti, R (2023-01-01)Asymmetric split ring resonators supporting high quality factor modes are investigated using aperture near-field microscopy. Modes of varying Q-factor are measured, and a novel cross-polarization measurement technique is ... -
Near-Field Spectroscopy of Individual Asymmetric Split-Ring Terahertz Resonators.
Lu, Y; Hale, LL; Zaman, AM; Addamane, SJ; Brener, I; Mitrofanov, O; Degl'Innocenti, R (American Chemical Society, 2023-08-03)Metamaterial resonators have become an efficient and versatile platform in the terahertz frequency range, finding applications in integrated optical devices, such as active modulators and detectors, and in fundamental ... -
Non-contact imaging of terahertz surface currents with aperture-type near-field microscopy
Norman, S; Seddon, J; Lu, Y; Hale, L; Zaman, AM; Addamane, S; Brener, I; Degl'Innocenti, R; Mitrofanov, O (Optica Publishing Group, 2024-06-17)Terahertz (THz) near-field imaging and spectroscopy provide valuable insights into the fundamental physical processes occurring in THz resonators and metasurfaces on the subwavelength scale. However, so far, the mapping ... -
