Nonlinear switching in multiple-core couplers.
Power-controlled switching between any output ports of different multiple-core nonlinear directional couplers is predicted. The input-output characteristic is calculated both at the half-beat length and the beat length. A second conservation law has been found in addition to the power conservation law.
