Nonlinear distortion of nonreciprocal transmission in parity-time-symmetric silicon micromechanical resonators
Abstract Parity-time (PT) symmetric resonators have an exact phase with real frequency eigenvalues and a broken phase with complex-conjugate frequency eigenvalues. In the presence of nonlinear gain, the PT-symmetric resonator exhibits nonreciprocal transmission when it is biased at the broken phase,...
