Light Amplification by Active Meta-mirrors
Ignas Lukosiunas, Kestutis Staliunas
We consider a scheme of thin films, deposited on periodically modulated amplifying materials. We show that the reflection from such meta-interface can undergo substantial amplifica…
Light Trapping by Non-Hermitian Thin Films
Lina Grineviciute, Ignas Lukosiunas, Julianija Nikitina +4
One of the exceptional features of non-Hermitian systems is the unidirectional wave interactions. Simultaneous modulation of the real and the imaginary part of the interaction pote…
Extremely Narrow, Sharp-Peaked Resonances at the Edge of the Continuum
Ignas Lukosiunas, Lina Grineviciute, Julianija Nikitina +2
We report a critical narrowing of resonances of a driven potential well, when their eigenfrequencies approach the edge of the continuum. The resonances also obtain unusual sharp-pe…
