METHOD FOR MANUFACTURING FIBRE PREFORM

摘要

The invention relates to a method for manufacturing a fibre preform and/or for modifying properties of the same by an ALD method. According to the invention, one or more fibre preforms are placed in an atomic layer deposition reactor and a first catalyst is supplied into a core of the fibre preform in order to produce a catalysing layer onto a surface of the core of the fibre preform. Next, one or more dopants are supplied into the core of the fibre preform, whereby the first catalyst causes two or more deposition layers to be formed onto the surface of the core of the fibre preform.
