Spatial and temporal propagation control in electro-optical components - involves double optical heterodyning to generate intermediate fields for nonlinear polarisation and refraction

摘要

A nonlinear refractive index of adjustable magnitude and sign is produced by transformation of a portion of the controlling and signalling light by optical heterodyne mixing into an intermediate field at the sum frequency. This field acts after a second heterodyne mixing in a nonlinearly refractive manner on the signal. The new nonlinear refractive index enables optical gates to be implemented as basic components of an optical computing technology and for fast switching in optical communication. ADVANTAGE - Power for soliton propagation and switching power for nonlinear optical gates can be reduced by several orders of magnitude.
