Nonlinear suppression of time reversals in PT-symmetric optical couplers
We reveal a generic connection between the effect of time reversals and nonlinear wave dynamics in systems with parity-time (PT) symmetry, considering a symmetric optical coupler with balanced gain and loss where these effects can be directly observed experimentally. We show that for intensities below a threshold level, the amplitudes oscillate between the waveguides, and the effects of gain and loss are exactly compensated after each period due to periodic time reversals. For intensities above...[Show more]
