Latest Patents

One of his latest patents is focused on stable polar optically nonlinear multilayer films and devices. This invention embodies an optical medium consisting of polar, multi-monomolecular layers of organic dye molecules with a net polar orientation, considerable second-order optical nonlinearity, and excellent thermal stability. The medium is prepared through repeated sequential depositions on a surface of multivalent metal ions, such as Zr.sup.4+, and organic dyes terminated with an acidic functionality, like phosphonic acid. The monolayers are deposited in the form of a multilayer film containing up to 1000 or more monolayers. The deposition process allows for application on substrates with diverse topography and configurations. Second harmonic generation (SHG) analysis confirms that the multilayers maintain uniform polar order, which does not diminish with an increasing number of monolayers. The inorganic interlayers provide orientational stability to the dye molecules at temperatures up to 150 degrees Celsius and higher. This optical medium is particularly useful in electrooptical or optical parametric devices, which include an optically nonlinear element and mechanisms for optical input and output.
