The ability to apply a planarizing, optically transparent, thermally stable polymer system that cures under relatively mild conditions has recently been demonstrated to have utility in the fabrication of multilayer devices such as advanced color liquid-crystal display31,32 The ability to apply this material as a dielectric or optical coating for thin-film electronics devices has also recently been demonstrated with the fabrication of an optical wave guiding device.33...

The incident angle dependences of measured reflectance of a probe beam at 543 nm are shown in Fig. 30 for a polystyrene film containing SP with a weight ratio of 10 1. Each dip shows the SPR for a silver film (a) and the guided TM wave mode for the composite thin film (b) before and (c,d) after excitation by a...

In the Cerenkov-type SHG the fundamental wave is guided in thin film, while the harmonic wave is outcoupled into the substrate (Fig. 44). It requires that the refractive indices of fhe subsfrafe af a) and 2co frequencies and the effective... 

Rutile possesses a high refractive index, thus making it an ideal material for passive optical wave-guides [17, 18]. Many of the mentioned applications forTi02 require the employment of thin films. CVD techniques have been used widely for the fabrication of such films. Titanium dioxide films have been prepared by the hydrolysis of TiCU [19, 20], by the reaction of TiCU with oxygen [21] and by the decomposition of titanium alkoxides, Ti(OR)4 (R = alkyl), under an atmosphere of oxygen [14, 15, 17, 18, 22]. Anastase-type SniTii 02 solid solutions have been prepared from the CVD of a mixture of TiCU and SnCU in the presence of water at 630°C [23].
