Plasmon Induced Transparency

AbstractRobust and dynamically polarization-controlled tunable plasmon induced transparency (PIT) resonance in designed finite-array nanostructures metasurface is demonstrated, where sharp resonance is guaranteed by design and protected against large geometrical imperfections even for micro-zone sub-array. By employing the explicit analysis of near-field characteristic in the reciprocal-space based on the momentum matching, and the far-field radiation features with point-scattering approach in real-space sparked from Huygens’s principles, the physics of interference resonance for plane-wave optical transmission and reflection of the metasurface is theoretically and thoroughly investigated. The distinctive polarization-selective and Q-tunable PIT shows robust features to performance degradations in traditional PIT system caused by inadvertent fabrication flaws or geometry asymmetry-variations, which paves way for the development of reconfigurable and flexible metasurface and, additionally, opens new avenues in robust and multifunctional controllable nanophotonics device design and applications.

The bandgaps of 1.187[Formula: see text]eV in non-irradiated nanostructured thin films of Cu(In,Ga)Se2 (CIGSe) and of 1.182[Formula: see text]eV in those films irradiated with 10[Formula: see text]keV hydrogen ions were determined using optical transmission and reflection spectroscopy at 4.2[Formula: see text]K. The observed reduction in the bandgap is assigned to the formation of secondary antisite defect complexes inducing band tails of the density of states in the valence band.

Transmission And Reflection

Optical transmission and reflection measurements are reported for the quasi one dimensional solids perylene-TCNQ (P1T1) and (perylene)3-TCNQ (P3T1) in the region from 300 to 1200 nm. Raman spectra of single crystals of both compounds were obtained from 20 to 3000 cm−1. With 457.9 nm excitation, combinations and overtones of perylene are observed for the first time. A complete Raman spectrum of perylene and its deuterated homologue including librations is thus obtained via selective resonance enhancement of that molecule.
