30 June 1995 Photonic applications of spatial soliton switches
Author Affiliations +
A novel switch is introduced which has the capability of interconnecting 1 input channel to N output channels in a single device, without crosstalk. It is based on the unique properties of spatial solitons which propagate without diffracting in space and create index channels which can be used to guide signals at the same or different frequencies. Angular scanning of the soliton channels is achieved by chirping the phase of the input wavefront. Some properties of the switch and the initial demonstration of soliton scanning in an AlGaAs planar waveguide at 1550 nm are discussed.
