Superradiance of a 2D-spaser array
A. V. Dorofeenko, A. A. Zyablovsky, A. P. Vinogradov +3
We demonstrate that interacting spasers arranged in a 2D array of arbitrary size can be mutually synchronized allowing them to supperradiate. For arrays smaller than the free space…
Loss compensation by spasers in metamaterials
E. S. Andrianov, D. G. Baranov, A. A. Pukhov +3
We show that exact loss compensation can be achieved in active metamaterials containing spasers pumped over a wide range of pumping values both below and above the spasing threshol…
Spaser Spectroscopy with Subwavelength Spatial Resolution
Yuriy E. Lozovik, Igor A. Nechepurenko, Alexander V. Dorofeenko +2
A new method for high-sensitivity subwavelength spectromicroscopy is proposed based on the usage of a spaser (near-field laser) in the form of a scanning probe microscope tip. The…
Comment on "Symmetry Breaking and Laser-Absorber Modes in Optical Scattering Systems"
A. A. Zyablovsky, A. P. Vinogradov, A. V. Dorofeenko +2
We show that PT-symmetry may exist only for isolated frequencies in optical systems. Therefore, PT-symmetry breaking transitions as the frequency is tuned up, discussed in Y. D. Ch…
