Phase transition in multimode nonlinear parity-time-symmetric waveguide couplers
Parity-time-symmetric ([Image: see text]-symmetric) optical waveguide couplers offer new possibilities for fast, ultracompact, configurable, all-optical signal processing. Here, we study nonlinear properties of finite-size multimode [Image: see text]-symmetric couplers and predict the nonlinear osci...
