Abstract
A planar waveguide device is described which can function as either a switching or power dividing element of a soliton transmission communication system operating at a selected central wavelength. The device has one input and two outputs and consists of two optical channel waveguides, in a coupler-like configuration, each of whose cores has a refractive index and dielectric constant with a dependence on the optical signal intensity which can balance a negative dispersion in the waveguide at dimensions compatible with monomode transmission of the selected central wavelength. It is a property of such waveguides that if the input to one channel waveguide is a temporal optical soliton, the output will also be a temporal soliton, and the output waveguide, or waveguides, from which it exits the device as well as the power of the switched or power divided signal at each output will be dependent upon the input soliton peak power. Such switching and power dividing circuits are useful at the input and output of soliton transmitting fibers as part of a high bit-rate (broadband) communication system.
