A method of manufacture of a substantially continuous circumferential coating on a non-planar substrate, is disclosed the method comprising the steps of: utilising a substantially non directional deposition technique and a substantially static substrate deposition geometry to deposit the coating. Coatings can be deposited which include piezoelectric modulation characteristics or electro-optic modulation characteristics. Ideally the coating has semiconducting properties. The type of coating ideally includes Zinc-Oxide coatings. The non directional deposition technique can comprise chemical vapor deposition via single source chemical vapor deposition. Suitable substrates include optical fibers which are clamped onto a substantially planar heating surface during the deposition. The optical fiber can be clamped at a portion of the length of the fiber which is located at one end of a heating surface during the deposition such that movement of a free end of the optical fiber is limited to movement substantially along the axis of the optical fiber.

Fabrication of Zinc Oxide films on non-planar substrates and the use thereof

The present invention relates to a method of growing a ZnO film using chemical vapour deposition (CVD), and to a ZnO film grown according to the method. The method includes providing a precursor in vapour form, the precursor substantially comprising Zn O(O CNR R ) , where R and R are any combination of akyl or perfluoroalkyl groups, and decomposing at least some of the vapour at the surface of the substrate such that the film of zinc oxide forms. An advantage of using this precursor material is that, unlike in the prior art, no deliberate introduction of water vapour to improve christallographic orientation is required. Higher purities in oxide films are produced.

Growth of ZnO film using single source CVD

A method is provided for forming a modified gel capable of forming a hydrophobic surface on which water has a contact angle of at least 150&deg;. Additionally, a method is provided for forming a hydrophobic coating from the modified gel. In some embodiments, the hydrophobic coating has an extremely high hydrophobicity with a contact angle in excess of 165&deg;, and good substrate adhesion. The method involves bonding a gel with particulate matter. It is believed that the chemical hydrophobicity of the gel is enhanced by the physical roughness of the particulate matter.
