Abstract
A method and apparatus are provided for drawing a self-aligned core fiber free of surface contamination and inserting the core fiber into a cladding material to make an optical fiber preform. Single or multi-mode optical fibers having high quality core-clad interfaces can be directly drawn from the preforms described herein.
Claims12
An apparatus for making an optical fiber preform comprising:
- a) a support structure;
- b) a carriage slidably mounted on said support structure and configured to translate with respect thereto in a first plane of movement;
- c) a platform movably connected to said support structure, said platform being dimensioned to receive a containment vessel and configured for movement in a second plane perpendicular to said first plane;
- d) means connected to said carriage for supporting at least a portion of a core fiber;
- e) means for heating said containment vessel to maintain a material in said containment vessel in a molten state;
- and
- f) means for moving said platform to axially align said containment vessel and said means for supporting at least a portion of a core fiber.
