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}…
A 5.7 THz GaN/AlGaN quantum cascade detector based on polar step quantum wells
Patrick Quach, Arnaud Jollivet, Andrey Babichev +12
We report on a GaN/AlGaN quantum cascade detector operating in the terahertz spectral range. The device was grown by metal organic chemical vapor deposition on a c-sapphire substra…
Optical bistable SOI micro-ring resonators for memory applications
Andrey A. Nikitin, Ilya A. Ryabcev, Aleksei A. Nikitin +7
The present work focuses on experimental investigations of a bistabile silicon-on-insulator (SOI) micro-ring resonator (MRR). The resonator exploits a continuous-wave operation of…
Observation of long turn-on delay in pulsed quantum cascade lasers
E. D. Cherotchenko, V. V. Dudelev, D. A. Mikhailov +16
We present an experimental study of the turn-on delay in pulsed mid-infrared quantum cascade lasers. We report the unexpectedly long delay time depending on the pumping current, wh…
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…
Controlling wave-front shape and propagation time with tunable disordered non-Hermitian multilayers
Denis Novitsky, Dmitry Lyakhov, Dominik Michels +3
Unique and flexible properties of non-Hermitian photonic systems attract ever-increasing attention via delivering a whole bunch of novel optical effects and allowing for efficient…
