Single-photon description of the lossless optical Y coupler
Christopher R. Schwarze, Anthony D. Manni, David S. Simon +1
Using symmetry considerations, we derive a unitary scattering matrix for a three-port optical Y-coupler or Y-branch. The result is shown to be unique up to external phase shifts. U…
Exceptional points in SSH-like models with hopping amplitude gradient
David S. Simon, Christopher R. Schwarze, Abdoulaye Ndao +1
The Su-Schrieffer-Heeger (SSH) system is a popular model for exploring topological insulators and topological phases in one dimension. Recent interest in exceptional points has led…
Enhanced-sensitivity interferometry with phase-sensitive unbiased multiports
Christopher R. Schwarze, David S. Simon, Alexander V. Sergienko
Here we introduce interferometric devices by combining optical feedback (cavities) with unbiased multiports, which unlike traditional beam dividers, allow light to reflect back out…
