CPA-lasing associated with the quasibound states in the continuum in asymmetric non-Hermitian structures
Denis V. Novitsky, Adia Canos Valero, Alexander Krotov +3
Non-Hermitian photonic systems with loss and gain attract much attention due to their exceptional abilities in molding the flow of light. Introducing asymmetry to the $\mathcal{PT}…
Quasi-bound states in the continuum induced by -symmetry breaking
Denis Novitsky, Alexander Shalin, Dmitrii Redka +2
Bound states in the continuum (BICs) enable unique features in tailoring light-matter interaction on nanoscale. These radiationless localized states drive theoretically infinite qu…
Purcell effect in PT-symmetric waveguides
Alina Karabchevsky, Andrey Novitsky, Fyodor Morozko
This chapter overviews the principles of the spontaneous emission rate increase, that is the Purcell effect, in relation to the photonic parity-time (PT) symmetry. Being focused on…
Unambiguous scattering matrix for non-Hermitian systems
Andrey Novitsky, Dmitry Lyakhov, Dominik Michels +3
symmetry is a unique platform for light manipulation and versatile use in unidirectional invisibility, lasing, sensing, etc. Broken and unbroken -symme…
Modal Purcell factor in -symmetric waveguides
Fyodor Morozko, Andrey Novitsky, Alina Karabchevsky
We study the spontaneous emission rate of a dipole emitter in -symmetric environment of two coupled waveguides using the reciprocity approach generalized to non-ortho…
Nano-scale tunable optical binding mediated by hyperbolic metamaterials
N. A. Kostina, D. A. Kislov, A. N. Ivinskaya +5
Carefully designed nanostructures can inspire new type of optomechanical interactions and allow surpassing limitations set by classical diffractive optical elements. Apart from str…
