Abstract
Power-controlled self-routing of pulses has been demonstrated in experiments employing different fiber versions of the nonlinear coupler, such as twin-core, birefringent, or rocking filler fibers. The nonlinear coupler has also the potential for controlling the routing of intense pulses by means of the relative phase of a weak signal.1 However in a one (or half) beat length coupler both type of operations require to operate at the critical power which is typically of the order of kilowatts.2,3
