Fundamentals of optical non-reciprocity based on optomechanical coupling
Mohammad-Ali Miri, Freek Ruesink, Ewold Verhagen +1
Optical isolation, non-reciprocal phase transmission and topological phases for light based on synthetic gauge fields have been raising significant interest in the recent literatur…
Nonreciprocity and magnetic-free isolation based on optomechanical interactions
Freek Ruesink, Mohammad-Ali Miri, Andrea Alù +1
Photonic nonreciprocal components, such as isolators and circulators, provide highly desirable functionalities for optical circuitry. This motivates the active investigation of mec…
Scattering properties of PT-symmetric objects
Mohammad-Ali Miri, Mohammad Amin Eftekhar, Margarida Facao +6
We investigate the scattering response of parity-time (PT) symmetric structures. We show that, due to the local flow of energy between gain and loss regions, such systems can defle…
Integrable nonlinear parity-time symmetric optical oscillator
Absar U. Hassan, Hossein Hodaei, Mohammad-Ali Miri +2
The nonlinear dynamics of a balanced parity-time symmetric optical microring arrangement are analytically investigated. By considering gain and loss saturation effects, the pertine…
Single mode lasing in transversely multi-moded PT-symmetric microring resonators
Hoseein Hodaei, Mohammad-Ali Miri, Absar U. Hassan +4
Single mode lasing is experimentally demonstrated in a transversely multi-moded InP-based semiconductor microring arrangement. In this system, mode discrimination is attained by ju…
A systematic approach for designing zero-DGD coupled multi-core optical fibers
Midya Parto, Mohammad Amin Eftekhar, Mohammad-Ali Miri +3
An analytical method is presented for designing N-coupled multi-core fibers with zero differential group delay. This approach effectively reduces the problem to a system of N-1 alg…
Observation of Parity-Time Symmetry in Optically Induced Atomic Lattices
Zhaoyang Zhang, Yiqi Zhang, Jiteng Sheng +6
We experimentally demonstrate PT-symmetric optical lattices with periodical gain and loss profiles in a coherently-prepared four-level N-type atomic system. By appropriately tuning…
