Nonlinear transition between PT-symmetric and PT-broken modes in coupled fiber lasers
Sergey V. Suchkov, Dmitry V. Churkin, Andrey A. Sukhorukov
We present a systematic analysis of the stationary regimes of nonlinear parity-time(PT) symmetric laser composed of two coupled fiber cavities. We find that power-dependent nonline…
In-line detection and reconstruction of multi-photon quantum states
Kai Wang, Sergey V. Suchkov, James G. Titchener +2
Integrated single-photon detectors open new possibilities for monitoring inside quantum photonic circuits. We present a concept for the in-line measurement of spatially-encoded mul…
Frequency comb generation in SNAP bottle resonators
Sergey V. Suchkov, Mikhail Sumetsky, Andrey A. Sukhorukov
We develop a theory of optical frequency comb generation in ultra-compact Surface Nanoscale Axial Photonic (SNAP) bottle microresonators, employing the nonlinear interaction of whi…
Whispering gallery modes in optical fibers based on reflectionless potentials
Sergey V. Suchkov, Mikhail Sumetsky, Andrey A. Sukhorukov
We consider an optical fiber with nanoscale variation of the effective fiber radius supporting whispering gallery modes slowly propagating along the fiber, and reveal that the radi…
Breathers in PT-symmetric optical couplers
I. V. Barashenkov, Sergey V. Suchkov, Andrey A. Sukhorukov +2
We show that the parity-time (PT) symmetric coupled optical waveguides with gain and loss support localised oscillatory structures similar to the breathers of the classical m…
Wave scattering on a domain wall in a chain of PT-symmetric couplers
Sergey V. Suchkov, Sergey V. Dmitriev, Boris A. Malomed +1
We study wave propagation in linear arrays composed of pairs of conjugate waveguides with balanced gain and loss, i.e. arrays of the PT-symmetric couplers, where the linear spectru…
