Perturbation-induced nonreciprocal transmission in nonlinear parity-time-symmetric silicon micromechanical resonators
Abstract Parity-time (PT) symmetric systems featuring balanced gain and loss, when biased in a broken phase, can produce nonreciprocal transmission in the presence of nonlinear gain. However, the weak coupling in the broken phase leads to high insertion loss during transmission. Here, we demonstrate...
