|Issue Date:||1-Nov-2010||Citation:||Tian, Z., Singh, R., Han, J., Gu, J., Xing, Q., Wu, J., Zhang, W. (2010-11-01). Terahertz superconducting plasmonic hole array.

ScholarBank@NUS Repository. https://doi.org/10.1364/OL.35.003586||Abstract:||We demonstrate a superconductor array of subwavelength holes with active thermal control over the resonant transmission induced by surface plasmon polaritons. The array was lithographically fabricated on a high-temperature yttrium barium copper oxide superconductor and characterized by terahertz time-domain spectroscopy. Weobserve a clear transition from a virtual excitation of the surface plasmon mode to a real surface plasmon mode. The highly controllable superconducting plasmonic crystals may find promising applications in the design of low-loss, largedynamic-range amplitude modulation and surface-plasmon-based terahertz devices. © 2010 Optical Society of America.||Source Title:||Optics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/98237||ISSN:||01469592||DOI:||10.1364/OL.35.003586|
