Light scattering in pseudo-passive media with uniformly balanced gain and loss
A. Basiri, I. Vitebskiy, T. Kottos
We introduce a class of metamaterials with uniformly balanced gain and loss associated with complex permittivity and permeability constants. The refractive index of such a balanced…
Optical Asymmetry Induced by PT-symmetric Nonlinear Fano Resonances
F. Nazari, N. Bender, H. Ramezani +3
We introduce a new type of Fano resonances, realized in a photonic circuit which consists of two nonlinear PT-symmetric micro-resonators side-coupled to a waveguide, which have lin…
Experimental Observation of Stabilization and Lasing Death via Asymmetric Gain
M. Chitsazi, S. Factor, J. Schindler +3
Using a pair of coupled LRC cavities we experimentally demonstrate that instabilities and amplification action can be tamed by a spatially inhomogenous gain. Specifically we observ…
PT-Symmetric Electronics
J. Schindler, Z. Lin, J. M. Lee +3
We show both theoretically and experimentally that a pair of inductively coupled active LRC circuits (dimer), one with amplification and another with an equivalent amount of attenu…
Bypassing the bandwidth theorem with PT symmetry
Hamidreza Ramezani, J. Schindler, F. M. Ellis +2
The beat time τ_{fpt} associated with the energy transfer between two coupled oscillators is dictated by the bandwidth theorem which sets a lower bound τ_{fpt}\sim 1/δω. We show, b…
Taming chaos by impurities in two-dimensional oscillator arrays
M. Weiss, Tsampikos Kottos, T. Geisel
The effect of impurities in a two-dimensional lattice of coupled nonlinear chaotic oscillators and their ability to control the dynamical behavior of the system are studied. We sho…
