Oral/2010: Modified Fresnel Approach to Wave Propagation in a Gain Slab

Alexander Dorofeenko¹, Alexander Zyablovsky¹, Alexander Pukhov¹, Alexey Vinogradov¹
¹ITAE RAS, Moscow
Abstract: We analyze applicability of the ε'' < 0 approximation to wave propagation in active material, comparing the results to the FDTD-based calculation employing more general...

Poster/2010: The Borrmann Effect at Spontaneous Emission in 1D Band Gap Structure

Alexander Pukhov¹, Alexander Dorofeenko¹, Alexey Vinogradov¹
¹ITAE RAS, Russia
Abstract: Spontaneous emission of a quantum dot placed in a 1D photonic band gap structure is analytically studied. Part of energy which remains nonradiated is obtained....

Oral/2012: Spaser for Sensing Applications

Alexander Dorofeenko¹, Igor Nechepurenko¹, Yuriy Lozovik², Eugeny Andrianov¹, Alexander Pukhov¹
¹ITAE RAS, Moscow, Russia
²Institute of Spectroscopy RAS, Moscow Region, Troitsk, Russia
Abstract: A new method of high-sensitive subwavelength spectromicroscopy is proposed based on usage of near field of spaser having a form of a tip of scanning...

Oral/2012: Using Spaser-Effect For Loss Compensation In Metamaterials

Alexey Vinogradov¹, Eugenii Andrianov¹, Alexander Pukhov¹, Alexander Dorofeenko¹, Alexander Lisyansky²
¹ITAE RAS, 13 Izhorskaya, Moscow 125412, Russia
²Department of Physics, Queens College of the City University of New York, Flushing, NY 11367
Abstract: We study possibilities for compensation of Joule losses in metamaterials by using spasers in both above and below pumping thresholds. For both above- and below...

Poster/2012: Optical Bistability in Spaser Chains

Alexander Pukhov¹, Eugeny Andrianov¹, Alexey Vinogradov¹, Alexander Dorofeenko¹, Alexander Lisyansky²
¹ITAE RAS, Moscow, Russia
²Department of Physics, Queens College of the City University of New York
Abstract: Optical bistability of a spaser and criteria of its appearance are studied theoretically. The effective transmission coefficient of a spaser is calculated. This allows for...

Poster/2012: Spaser Chains

Eugeny Andrianov¹, Alexander Pukhov¹, Alexey Vinogradov¹, Alexander Dorofeenko¹, Alexander Lisyansky²
¹ITAE RAS, Moscow, Russia
²Department of Physics, Queens College of the City University of New York
Abstract: We show that depending on the values of the coupling constants, two scenarios for the stationary behavior of a chain of interacting spasers may be...

Poster/2012: Superradiance and Synchronization of 2D Spaser Array

Alexander Zyablovsky¹, Alexander Dorofeenko¹, Alexey Vinogradov¹, Eugene Andrianov¹, Alexander Pukhov¹, Alexander Lisyansky²
¹Institute for Theoretical and Applied Electromagnetics, 13 Izhorskaya, Moscow 125412, Russia
²Department of Physics, Queens College of the City University of New York, Flushing, NY 11367
Abstract: Recently [E. S. Andrianov et al. Phys. Rev. B, 85, 165419 (2012)] it has been shown that a 1D chain of spasers may be synchronized...
