Confinement-Induced Resonances in Low-Dimensional Quantum Systems [PDF]
, 2010 We report on the observation of confinement-induced resonances in strongly interacting quantum-gas systems with tunable interactions for one- and two-dimensional geometry.

Non-Hermiticity-induced wave confinement and guiding in loss-gain-loss three-layer systems [PDF]
Physical Review A, 2016 Following up on previous studies on parity-time-symmetric gain-loss bi-layers, and inspired by formal analogies with plasmonic waveguides, we study non-Hermiticity-induced wave confinement and guiding phenomena that can occur in loss-gain-loss three-layers. By revisiting previous well-established "gain-guiding" concepts, we investigate analytically and

Ultra-large bandwidth hollow-core guiding in all-silica Bragg fibers with nano-supports [PDF]
, 2004 We demonstrate a new class of hollow-core Bragg fibers that are composed of concentric cylindrical silica rings separated by nanoscale support bridges. We theoretically predict and experimentally observe hollow-core confinement over an octave frequency ...

Confinement Loss and GVD for HF and AHAOF by FEM
International Journal of Optics and Applications, 2012 An analysis of the confinement loss and Group Velocity Dispersion (GVD) due to their importance is performed by means of the fin ite element method for t wo kinds of fibers , an Air-Hole Assisted Optical Fiber (AHA OF) and a Holy Fiber (HF). Both structures are based on a subset of a triangular array of cy lindrical air holes; the cross sections of ...

Inelastic Confinement-Induced Resonances in Low-Dimensional Quantum Systems
, 2011 A theoretical model is presented describing the confinement-induced resonances observed in the recent loss experiment of Haller et al. [Phys. Rev. Lett. 104, 153203 (2010)].

Impact of Localized Radiative Loss on Inertial Confinement Fusion Implosions
Physical Review Letters, 2020 The impact to fusion energy production due to the radiative loss from a localized mix in inertial confinement implosions using high density carbon capsule targets has been quantified. The radiative loss from the localized mix and local cooling of the reacting plasma conditions was quantified using neutron and x-ray images to reconstruct the hot spot ...

Highly confined low-loss plasmons in graphene–boron nitride heterostructures [PDF]
Nature Materials, 2014 Graphene plasmons were predicted to possess ultra-strong field confinement and very low damping at the same time, enabling new classes of devices for deep subwavelength metamaterials, single-photon nonlinearities, extraordinarily strong light-matter interactions and nano-optoelectronic switches.

Overcoming Si3N4 film stress limitations for High Quality factor ring resonators
, 2013 Silicon nitride (Si3N4) ring resonators are critical for a variety of photonic devices. However the intrinsically high film stress of silicon nitride has limited both the optical confinement and quality factor (Q) of ring resonators.
