摘要： Applicants have discovered that by heating cured polymer-coated fiber at temperatures of 100.degree. C. or more, they can enhance the fiber pullout strength by 25% or more. This postcure heating can advantageously be done off-line by placing loosely wound fiber in a heated oven. Alternatively the postcure heating can be done on-line by reel-to-reel passage of the fiber through a heated furnace. Preferred temperatures are in the range 100.degree. C.-300.degree. C.

摘要： Applicants have discovered that low pullout strength of optical fiber is attributable to volatile, unreacted monomers and impurities which result from the incomplete polymerization of liquid coating materials. They have further discovered that removing these unreacted liquids as by heating in air, heating in vacuum or by application of a solvent mixture improves fiber coating adhesion. By heating cured polymer-coated fiber in air at temperatures of 100.degree. C. or more, the fiber pullout strength is enhanced by 25% or more. This postcure heating can advantageously be clone off-line by placing loosely wound fiber in a heated oven. Alternatively, the postcure heating can be done on-line by reel-to-reel passage of the fiber through a heated furnace. Preferred temperatures are in the range 100.degree. C.-300.degree. C. Even greater enhancement of pullout strength can be effected by heating in vacuum or by solvent extraction.

摘要： This invention embodies an optical medium which consists 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 by repeated sequential depositions on a surface of multivalent metal ions, e.g. Zr.sup.4+, and organic dyes terminated with an acidic functionality, e.g. a phosphonic acid, followed by activation of the surface for the next deposition sequence. The monolayers are deposited in the form of a multilayer film containing up to 1000 or more monolayers. The monolayers are deposited from liquid solutions; therefore they may be deposited on substrates having diverse topography and configurations. Second harmonic generation (SHG) analysis establishes that the multilayers have uniform polar order which does not decrease with increasing numbers of monolayers in the film. As determined by SHG, the inorganic interlayers impart orientational stability to the dye molecules up to 150.degree. C. and higher. The optical medium is useful in electrooptical or optical parametric devices comprising an optically nonlinear element and means for providing an optical input to and output from said element wherein said element comprises the nonlinear optical medium supported on a suitable base. When said device is employed in an electrooptic mode, it includes means for applying an electric field and/or optical input to said element for altering an optical property thereof.
