“…Optical losses are measured using a light beam from a 10 mW polarized He-Ne laser (L = 632.8 nm) coupled into the waveguide. The scattered guided light is directly analyzed by a microcomputer-assisted video camera system [3]. Refractive indices and thickness of the films are determined by m-Line spectroscopy [4].…”

Abstract. ZrO2 waveguides are prepared by the sol-gel process from a solution containing zirconium n-propoxide and acetylacetone in propanol-2. Structural characterizations are investigated for different annealing temperatures using suitable techniques including Waveguide Raman Spectroscopy, Electron Microscopy and Atomic Force Microscopy. Films are amorphous at 300~ and the pure ZrO2 tetragonal crystalline phase appears beyond 400~ Crystallized films present a dense, uniform and polycrystalline structure made up by randomly oriented nanocrystallites, the diameter of which increases from 38/~ at 400~ to 53/~ at 600~ Waveguides are at least monomode TE0 at 632.8 nm. At this wavelength, optical losses are about 0.8 4-0.2 dB/cm for amorphous layers and increase up to 2.5 4-0.4 dB/cm for 600~ heat-treated waveguides.

Sol–gel is a versatile technology offering advantageous processing of complex shapes as well as material compositions. In the realm of optical communications, the applicability of a number of dielectric and hybrid materials in various photonic devices makes the technology particularly appealing vis‐a‐vis the vapor‐phase methods that dominate the field today. One can find numerous reports of sol–gel processing for photonic components, although instances where this has been developed for product manufacture are far fewer. Here, we examine the different classes of optical communication devices from fibers to waveguides to photonic crystals and the ability of sol–gel processing to address their needs. Successful deployment appears to depend on two aspects: making innovative modifications to the traditional concept and developing supporting technologies to overcome the key drawbacks.
