Multiqubit entanglement and quantum phase gates with epsilon-near-zero plasmonic waveguides
Ying Li, Christos Argyropoulos
Multiqubit entanglement is extremely important to perform truly secure quantum optical communication and computing operations. However, the efficient generation of long-range entan…
Plasmonic Waveguides to Enhance Quantum Electrodynamic Phenomena at the Nanoscale
Ying Li, Christos Argyropoulos
The emerging field of plasmonics can lead to enhanced light matter interactions at extremely nanoscale regions. Plasmonic (metallic) devices promise to efficiently control both cla…
Plasmonic random laser on an optical fiber tip
Dipendra S. Khatri, Ying Li, Jiyang Chen +5
Random lasing occurs as the result of a coherent optical feedback from multiple scattering centers. Here, we demonstrate that plasmonic gold nanostars are efficient light scatterin…
Epsilon-near-zero plasmonic waveguides to enhance nonlinear coherent light-matter interactions
Ying Li, Christos Argyropoulos
We demonstrate a way to coherently control light at the nanoscale and achieve coherent perfect absorption (CPA) by using epsilon-near-zero (ENZ) plasmonic waveguides. The presented…
Extreme Sub-Wavelength Light Confinement in Plasmonic Film-Coupled Nanostar Resonators
Negar Charchi, Ying Li, Margaret Huber +4
Confining light in extreme subwavelength scales is a tantalizing task. In this work, we report a study of individual plasmonic film-coupled nanostar resonators where plasmonic opti…
Exceptional points and spectral singularities in active epsilon-near-zero plasmonic waveguides
Ying Li, Christos Argyropoulos
We present a nanoscale active plasmonic waveguide system consisting of an array of periodic slits that can exhibit exceptional points and spectral singularities leading to several…
Resonance Energy Transfer and Quantum Entanglement Mediated by Epsilon-Near-Zero and Other Plasmonic Waveguide Systems
Ying Li, Andrei Nemilentsau, Christos Argyropoulos
The entanglement and resonance energy transfer between two-level quantum emitters are typically limited to sub-wavelength distances due to the inherently short-range nature of the…
Tunable nonlinear coherent perfect absorption with epsilon-near-zero plasmonic waveguides
Ying Li, Christos Argyropoulos
We propose a scheme to realize nonlinear coherent perfect absorption (CPA) at the nanoscale using epsilon-near-zero (ENZ) plasmonic waveguides. The general conditions to achieve CP…
Controlling collective spontaneous emission with plasmonic waveguides
Ying Li, Christos Argyropoulos
We demonstrate a plasmonic route to control the collective spontaneous emission of two-level quantum emitters. Superradiance and subradiance effects are observed over distances com…
Vortex Laser at Exceptional Point
Xing-Yuan Wang, Hua-Zhou Chen, Ying Li +2
The optical vortices carrying orbital angular momentum (OAM) are commonly generated by modulating the available conventional light beam. This article shows that a micro-laser opera…
