摘要： An optical article is disclosed capable of modulating the reflection of electromagnetic radiation containing a reflective metal layer having a thickness of less than 0.5 mu m, an optical coupler for directing polarized electromagnetic radiation to the reflective metal layer and serving as a support for the device, a first dielectric layer (103) interposed between the reflective metal layer (105) and the support having a thickness in the range of from 0.1 to 10 times the wavelength of the electromagnetic radiation, a second dielectric layer (107) adjacent the reflective metal layer exhibiting a refractive index which differs from that of the first dielectric layer by less than 20 percent and can be adjusted by an applied electrical potential gradient, and means (109) for variably applying an electrical potential to a surface of the second dielectric layer remote from the reflective metal layer. The second dielectric layer is a polymeric layer coated on the reflective metal layer exhibiting a second order polarization susceptibility greater than 10 electrostatic units and comprised of polar aligned molecular dipoles having an electron donor moiety linked through a conjugated pi bonding system to an electron acceptor moiety.

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 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.

摘要： HIGH x(2) OPTICAL ARTICLE WITH IMPROVED BUFFER LAYER An optical article for the propagation of electromagnetic radiation is disclosed comprised of an electrically conductive support on which a poled polymeric film exhibiting a glass transition temperature of at least 80.degree.C and a second order polarization susceptibility greater than 10-9 electrostatic units is formed. A layer for enhancing the transmission of electromagnetic radition is interposed between the electrically conductive support and the poled polymeric film. The transmission enhancement layer is an amorphous layer of at least 0.5 .mu.m in thickness having a refractive index less than that of the polymeric film and a resistance less than 10 times that of the polymeric film. The transmission enhancement layer being comprised of a mixture of (a) at least one metal oxide or fluoride and (b) a low molecular weight aromatic compound.
