We propose and analyze a scheme to enhance optomechanically-induced-transparency (OMIT) based on parity-time-symmetric optomechanical system. Our results predict that an OMIT window which does not exist originally can appear in weak optomechanical coupling and driving system via coupling an auxiliary ...
parity‐time symmetryAs an elementary processor of neural networks, a neuron performs exotic dynamic functions, such as bifurcation, repetitive firing, and oscillation quenching. To achieve ultrafast neuromorphic signal processing, the realization of photonic equivalents to neuronal dynamic functions has ...

which is difficult to generate and maintain. This has been a major roadblock to realize practical NOSP systems for high-speed, high-capacity optical communications. Here, we propose using a parity-time (PT) symmetric microresonator system to significantly enhance the light intensity and support high...
We introduced a coupled waveguide arrays with intrinsic Parity-Time (PT)-symmetric nonlinearity. The system is described by a set of coupled Schr枚dinger equations with linear couplings and a complex nonlinearity. Two-component soliton modes are found to exist in this system. The stability of the...
an optical potential, we can then design a PT-symmetric systemby satisfying the conditions n R (x) =n R (−x) and n I (x) =−n I (−x). In other words, the refractive-index profile must be an even function of position x whereas the gain/loss distribution should be ...
