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…

Causality and phase transitions in PT-symmetrical optical systems
A. A. Zyablovsky, A. P. Vinogradov, A. V. Dorofeenko +2
We discuss phase transitions in PT-symmetric optical systems. We show that due to frequency dispersion of the dielectric permittivity, an optical system can have PT-symmetry at iso…
