Plasmon-Enhanced Second-Harmonic Generation in Atomically Thin Crystalline Silver Nanostructures
Saad Abdullah, Philipp K. Jenke, Andrew P. Weber +8
The intrinsically weak nonlinear optical response of existing materials, further constrained by symmetry-forbidden second-order processes in centrosymmetric media, severely limits…
Pathway to Optical-Cycle Dynamic Photonics: Extreme Electron Temperatures in Transparent Conducting Oxides
Jae Ik Choi, Vahagn Mkhitaryan, Colton Fruhling +4
We theoretically demonstrate that transparent conducting oxides (TCOs) exhibit oscillatory and sign-reversing dynamic modulation in transmittance on the order of a few optical cycl…
Topology-Optimized Dielectric Cavities for Enhanced Excitonic Light Emission from
Owen Matthiessen, Brandon Triplett, Omer Yesilyurt +14
Photonic inverse design and, especially, topology optimization, enable dielectric cavities with deeply sub-diffraction mode volumes and high quality factors, thus offering a powerf…
Atomically thin silver films for enhanced nanoscale nonlinear optics
Philipp K. Jenke, Saad Abdullah, Andrew P. Weber +8
The inherently weak nonlinear optical response of bulk materials remains a fundamental limitation in advancing photonic technologies. Nanophotonics addresses this challenge by tail…
Floquet Engineering of Polaritonic Amplification in Dispersive Photonic Time Crystals
Mustafa Goksu Ozlu, Vahagn Mkhitaryan, Colton B. Fruhling +2
In this study, we investigate the dynamics of dispersive photonic time crystals (PTCs) and their potential applications for controlling light-matter interaction. By employing the L…
Plasmonic Enhancement of Second Harmonic Generation in Weyl Semimetal TaAs
Morris M. Yang, Mustafa Ozlu, Samuel Peana +9
In this work a hybrid nanoplasmonic-Weyl Semimetal (WSM) structure is realized for the first time utilizing silver nanopatch antennas and WSM Tantalum Arsenide (TaAs). The studied…
Ultrafast broadband tuning of resonant optical nanostructures using phase change materials
Miquel Rudé, Vahagn Mkhitaryan, Arif E. Cetin +6
The functionalities of a wide range of optical and opto-electronic devices are based on resonance effects and active tuning of the amplitude and wavelength response is often essent…
