    "abstract": "Linear and nonlinear directional couplers are currently used in fiber optics\ncommunications. They may also play a role in multiphoton approaches to quantum\ninformation processing if accurate control is obtained over the phases and\npolarizations of the signals at the output of the coupler. With this\nmotivation, the constants of motion of the coupler equation are used to obtain\nan explicit analytical solution for the nonlinear coupler.",
