ABSTRACT:
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.
