Lowering the lasing threshold of distributed feedback lasers with loss
V. Yu. Shishkov, A. A. Zyablovsky, E. S. Andrianov +4
We study laser generation in 1D distributed feedback lasers with amplifying and lossy layers. We show that when the lasing frequency differs from the transition frequencies of the…
Superradiance of a subwavelength array of independent classical nonlinear emitters
N. E. Nefedkin, E. S. Andrianov, A. A. Zyablovsky +3
We suggest a mechanism for the emergence of a superradiance burst in a subwavelength array of nonlinear classical emitters. We assume that the emitters interact via their common fi…
Parametric instability of non-Hermitian systems near the exceptional point
Alexander A. Zyablovsky, Evgeny S. Andrianov, Alexander A. Pukhov
In contrast to Hermitian systems, eigenstates of non-Hermitian ones are in general nonorthogonal. This feature is most pronounced at exceptional points where several eigenstates ar…
