On-chip plasmon-induced transparency based on plasmonic coupled nanocavities. [PDF]
Sci Rep, 2014 On-chip plasmon-induced transparency offers the possibility of realization of ultrahigh-speed information processing chips. Unfortunately, little experimental progress has been made to date because it is difficult to obtain on-chip plasmon-induced transparency using only a single meta-molecule in plasmonic circuits.

Magnetic plasmon induced transparency in three-dimensional metamolecules
Nanophotonics, 2012 In a laser-driven atomic quantum system, a continuous state couples to a discrete state resulting in quantum interference that provides a transmission peak within a broad absorption profile the so-called electromagnetically induced transparency (EIT). In

Plasmon-Induced Transparency Based on Triple Arc-Ring Resonators. [PDF]
Materials (Basel), 2018 This paper presents a plasmon-induced transparency (PIT) using an easy-fabricating metamaterial composed of three pieces of metallic arc-rings on top of a dielectric substrate. The transmission of the transparent peak of 1.32 THz reaches approximately 93%.

Ultrashort Self-Induced Transparency Plasmon Solitons [PDF]
Physical Review Letters, 2013 We study the interband self-induced transmission of surface plasmon polaritons in a gold film surrounded by an external Kerr medium. We model the optical propagation by using a version of the generalized nonlinear Schrodinger equation for the field envelope coupled to Bloch equations for valence electrons of gold, predicting self-induced transparency ...
