Breakthroughs in Photonics 2014: Relaxed Total Internal Reflection
Saman Jahani, Zubin Jacob
Total internal reflection (TIR) is a ubiquitous phenomenon used in photonic devices ranging from waveguides and resonators to lasers and optical sensors. Controlling this phenomeno…
Optical Characterization of Epsilon-Near-Zero, Epsilon-Near-Pole and Hyperbolic Response in Nanowire Metamaterials
Ryan Starko-Bowes, Jon Atkinson, Ward Newman +6
We report on the optical and physical characterization of metallic nanowire (NW) metamaterials fabricated by electrodeposition of ~30 nm diameter gold nanowires in nano-porous anod…
Universal Spin-Momentum Locked Optical Forces
Farid Kalhor, Thomas Thundat, Zubin Jacob
Evanescent electromagnetic waves possess spin-momentum locking, where the direction of propagation (momentum) is locked to the inherent polarization of the wave (transverse spin).…
Ferrell-Berreman modes in plasmonic epsilon-near-zero media
Ward D. Newman, Cristian L. Cortes, Jon Atkinson +3
We observe unique absorption resonances in silver/silica multilayer-based epsilon-near-zero (ENZ) metamaterials that are related to radiative bulk plasmon-polariton states of thin-…
Universal spin-momentum locking of evanescent waves
Todd Van Mechelen, Zubin Jacob
We show the existence of an inherent property of evanescent electromagnetic waves: spin-momentum locking, where the direction of momentum fundamentally locks the polarization of th…
Ideal near-field thermophotovoltaic cells
Sean Molesky, Zubin Jacob
We ask the question, what are the ideal characteristics of a near-field thermophotovoltaic cell? Our search leads us to a reformulation of near-field radiative heat transfer in ter…
