HIGH X (2) OPTICAL ARTICLE

摘要

A nonlinear optical article for the controlled propagation of electromagnetic radiation is disclosed. The article includes a reflective metal layer (103) having a thickness in the range of from 100 to 1000 ANGSTROM and work function in the range of from 2.5 to 4.5 eV, an optical coupler, a dielectric medium comprised of a poled polymeric layer (107) exhibiting a glass transition temperature of at least 50 DEG C and a second order polarization susceptibility greater than 10<-><9> electrostatic units, and means (109) for variably applying an electrical potential to a surface of the dielectric medium remote from the reflective metal layer. A protective metal fluoride or oxide layer (105) having a thickness of less than 0.1 mu m is interposed between the reflective metal layer and the poled polymeric layer.
