Nanostructured optical waveguide with a highly confined mode
E. D. Chubchev, I. A. Nechepurenko, A. V. Dorofeenko +2
We propose a transmission line working at telecom wavelengths with cross section as small as , which is 1.6 times smaller than that of optimized silicon waveguide. The prop…
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…
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…
