Non-Planck thermal emission from two-level media
Igor A Nechepurenko, Denis G Baranov
Thermal emission is a universal phenomenon of stochastic electromagnetic emission from an object composed of arbitrary materials at elevated temperatures. A defining feature of thi…
Nanostructured optical waveguide with a highly confined mode
E. D. Chubchev, I. A. Nechepurenko, A. V. Dorofeenko +2
We propose a transmission line working at telecom wavelengths with cross section as small as , which is 1.6 times smaller than that of optimized silicon waveguide. The prop…
Thermal Switching of Lasing Regimes in Heavily Doped Er3+ Fiber Lasers
Alexander M. Smirnov, Alexey P. Bazakutsa, Yuri K. Chamorovskiy +3
A pulsed regime of short-cavity, heavily erbium-doped fiber lasers is of high interest for its possible applications in telecommunications and sensorics. Here, we demonstrate these…
Nanophotonic engineering of far-field thermal emitters
Denis G. Baranov, Yuzhe Xiao, Igor A. Nechepurenko +3
Thermal emission is a ubiquitous and fundamental process by which all objects at non-zero temperatures radiate electromagnetic energy. This process is often presented to be incoher…
Surface plasmon polaritons in the ultraviolet region
E. D. Chubchev, I. A. Nechepurenko, A. V. Dorofeenko +2
We study a surface plasmon polariton mode that is strongly confined in the transverse direction and propagates along a periodically nanostructured metal-dielectric interface. We sh…
Plasmonic nanolaser for intracavity spectroscopy and sensorics
P. Melentyev, A. Kalmykov, A. Gritchenko +13
We demonstrate intracavity plasmonic laser spectroscopy using a plasmonic laser created from a periodically-perforated silver film with a liquid gain medium. An active zone of the…
Approach for describing spatial dynamics of quantum light-matter interaction in dispersive dissipative media
A. A. Zyablovsky, E. S. Andrianov, I. A. Nechepurenko +3
Solving the challenging problem of the amplification and generation of an electromagnetic field in nanostructures enables to implement many properties of the electromagnetic field…
Optimum gain for plasmonic distributed feedback lasers
A. A. Zyablovsky, I. A. Nechepurenko, E. S. Andrianov +4
Although nanolasers typically have low Q-factors and high lasing thresholds, they have been successfully implemented with various gain media. Intuitively, it seems that an increase…
Anisotropy-assisted non-scattering coherent absorption of surface plasmon-polaritons
Anton I. Ignatov, Igor A. Nechepurenko, Denis G. Baranov
The ability to control propagation of electromagnetic guided modes lies at the heart of integrated nanophotonics. Surface plasmon-polaritons are a class of guided modes which can b…
Self-consistent Description of Graphene Quantum Amplifier
Yu. E. Lozovik, I. A. Nechepurenko, A. V. Dorofeenko +3
High level of dissipation in normal metals makes challenging development of active and passive plasmonic devices. One possible solution to this problem is to use alternative materi…
Graphene Spaser Description by Rate Equations
Yu. E. Lozovik, I. A. Nechepurenko, A. V. Dorofeenko +1
In this paper a surface plasmon polariton laser (spaser), which generates surface plasmons in graphene nanoflake, is considered. The peculiarities of spaser, such as strong materia…
Transition to lasing induced by resonant absorption
I. A. Nechepurenko, D. G. Baranov, A. V. Dorofeenko
We theoretically demonstrate that increase of absorption with constant gain in laser systems can lead to onset of laser generation. This counter-intuitive absorption induced lasing…
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…
Channel spaser
A. A. Lisyansky, I. A. Nechepurenko, A. V. Dorofeenko +2
We show that net amplification of surface plasmons is achieved in channel in a metal plate due to nonradiative excitation by quantum dots. This makes possible lossless plasmon tran…
