Dissipation-driven quantum phase transitions in collective spin systems
S. Morrison, A. S. Parkins
We consider two different collective spin systems subjected to strong dissipation -- on the same scale as interaction strengths and external fields -- and show that either continuo…
Observation of Enhanced Beaming from Photonic Crystal Waveguides
Steven K. Morrison, Yuri S. Kivshar
We report on the experimental observation of the beaming effect in photonic crystals enhanced via surface modes. We experimentally map the spatial field distribution of energy emit…
Tunable split-ring resonators for nonlinear negative-index metamaterials
Ilya V. Shadrivov, Steven K. Morrison, Yuri S. Kivshar
We study experimentally the dynamic tunability and self-induced nonlinearity of split-ring resonators incorporating variable capacitance diodes. We demonstrate that the eigenfreque…
Tamm states and nonlinear surface modes in photonic crystals
Steven K. Morrison, Yuri S. Kivshar
We predict the existence of surface gap modes, known as Tamm states for electronic systems, in truncated photonic crystals formed by two types of dielectric rods. We investigate th…
Beaming effect from increased-index photonic crystal waveguides
Steven K. Morrison, Yuri S. Kivshar
We study the beaming effect of light for the case of increased-index photonic crystal (PhC) waveguides, formed through the omission of low-dielectric media in the waveguide region.…
Engineering of directional emission from photonic crystal waveguides
Steven K. Morrison, Yuri S. Kivshar
We analyze, by the finite-difference time-domain numerical methods, several ways to enhance the directional emission from photonic crystal waveguides through the beaming effect rec…
