Unidirectional Amplification in the Frozen Mode Regime Enabled by a Nonlinear Defect
Serena Landers, William Tuxbury, Ilya Vitebskiy +1
A stationary inflection point (SIP) is a spectral singularity of the Bloch dispersion relation of a periodic structure where the first and the second derivatives of with…
Nonlinear Wavepacket Dynamics in Proximity to a Stationary Inflection Point
Serena Landers, Arkady Kurnosov, William Tuxbury +2
A stationary inflection point (SIP) in the Bloch dispersion relation of a periodic waveguide is an exceptional point degeneracy where three Bloch eigenmodes coalesce forming the so…
Optical Limiter Based on PT-Symmetry Breaking of Reflectionless Modes
F. Riboli, R. Kononchuk, F. Tommasi +8
The application of parity-time (PT) symmetry in optics, especially PT-symmetry breaking, has attracted considerable attention as a novel approach to controlling light propagation.…
Frozen Mode Regime in an Optical Waveguide With Distributed Bragg Reflector
Nathaniel Furman, Tarek Mealy, Md Shafiqul Islam +5
We introduce a glide symmetric optical waveguide exhibiting a stationary inflection point (SIP) in the Bloch wavenumber dispersion relation. An SIP is a third order exceptional poi…
Lasing at a Stationary Inflection Point
Albert Herrero-Parareda, Nathaniel Furman, Tarek Mealy +4
The concept of lasers based on the frozen mode regime in active periodic optical waveguides with a 3rd-order exceptional point of degeneracy (EPD) is advanced. The frozen mode regi…
Design of a Modified Coupled Resonators Optical Waveguide Supporting a Frozen Mode
Mohamed Y. Nada, Tarek Mealy, Md Shafiqul Islam +5
We design a three-way silicon optical waveguide with the Bloch dispersion relation supporting a stationary inflection point (SIP). The SIP is a third order exceptional point of deg…
