| 简介 |
PURPOSE : A method of fabricating glass bodies containing an LVP(low vapor pressure) precursor dopant such as rare earth elements is provided to manage an LVP precursor without defects of typical liquid aerosol systems, to be applied to MCVD system or other optical fiber production systems such as OVD and VAD by filtering aerosol particles with size out of the desired range.
CONSTITUTION : The method includes the steps of : (a) forming first aerosol which contains first particles of first LVP precursor, the first particles only having the first LVP precursor; (b) generating vapor form of ingredients (wherein (a) and (b) steps are performed far from a vapor deposition device to form a glass body); (c) conducting convection of the aerosol and the vapor from (a) and (b) steps to the vapor deposition device containing a substrate; and (d) forming at least one doped layer, which contains the dopant of the aerosol and the vapor after the convection, on the surface of the substrate.
