Dual-band plasmonic resonator based on Jerusalem cross-shaped nanoapertures

Hatice Altug, Arif Engin Cetin, Shyamsunder Erramilli

In this paper, we both experimentally and numerically introduce a dual-resonant metamaterial based on subwavelength Jerusalem cross-shaped apertures. We numerically investigate the physical origin of the dual-resonant behavior, originating from the constit ...

Nonlinear Midinfrared Photothermal Spectroscopy Using Zharov Splitting and Quantum Cascade Lasers

Hatice Altug, Mi Kyung Hong, Shyamsunder Erramilli

We report on the Mid-infrared nonlinear photothermal spectrum of the neat liquid crystal 4-octyl-4'-cyanobiphenyl (8CB) using a tunable Quantum Cascade Laser (QCL). The nonequilibrium steady state characterized by the nonlinear photothermal infrared respon ...

Dynamic Tuning of Surface Plasmon Polaritons via Thermally Controlled Liquid Crystals

Min Huang, Hatice Altug, Arif Engin Cetin, Shyamsunder Erramilli

We present a thermally controlled plasmonic substrate in contact with a liquid crystal offering spectral tunings similar to 18.7 nm within similar to 18 degrees C at LC nematic phase. Nematic/ isotropic transition also enables similar to 12 nm spectral cha ...

Engineered Absorption Enhancement and Induced Transparency in Coupled Molecular and Plasmonic Resonator Systems

Hatice Altug, Shyamsunder Erramilli

Coupled plasmonic resonators have become the subject of significant research interest in recent years as they provide a route to dramatically enhanced light-matter interactions. Often, the design of these coupled mode systems draws intuition and inspiratio ...
