Extra Loss-free Non-Hermitian Engineered Single Mode Laser Systems
Mohammad H. Teimourpour, Hamed Dalir, Elham Heidari +4
In a laser system non-Hermitian methods such as Parity-Time (PT) Symmetry and Supersymmetry (SUSY) have shown and demonstrated the ability to suppress unwanted lasing modes and, th…
Experimental Realization of Multiple Topological Edge States in a One-Dimensional Photonic Lattice
Zhifeng Zhang, Mohammad Teimourpour, Jake Arkinstall +5
Topological photonic systems offer light transport that is robust against defects and disorder, promising a new generation of chip-scale photonic devices and facilitating energy-ef…
Topological tight-binding models from non-trivial square roots
J. Arkinstall, M. H. Teimourpour, L. Feng +2
We describe a versatile mechanism that provides tight-binding models with an enriched, topologically nontrivial bandstructure. The mechanism is algebraic in nature, and leads to ti…
Non-Hermitian engineering of synthetic saturable absorbers
M. H. Teimourpour, A. Rahman, K. Srinivasan +1
We introduce a new type of synthetic saturable absorbers based on quantum inspired photonic arrays whose linear light transport characteristics can be derived via bosonic algebra.…
Non-Hermitian engineering of single mode two dimensional laser arrays
Mohammad H. Teimourpour, Li Ge, Demetrios N. Christodoulides +1
A new scheme for building two dimensional laser arrays that operate in the single supermode regime is proposed. This is done by introducing an optical coupling between the laser ar…
Computation of spontaneous emission dynamics in colored vacua
Mohammad Hosain Teimourpour, Ramy El-Ganainy
We present an efficient time domain numerical scheme for computing spontaneous emission dynamics in colored vacua. Starting from first principles, we map the unitary evolution of a…
Light transport in PT-invariant photonic structures with hidden symmetries
M. H. Teimourpour, R. El-Ganainy, A. Eisfeld +2
We introduce a recursive bosonic quantization technique for generating classical PT photonic structures that possess hidden symmetries and higher order exceptional points. We study…
