METHODS FOR PRODUCING HOLLOW-CORE OPTICAL FIBERS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240036249 titled 'METHODS FOR PRODUCING HOLLOW-CORE OPTICAL FIBERS

Simplified Explanation

The present disclosure is directed to methods for making an optical fiber by drawing it from a hollow-core preform. The preform includes an annular support structure with an inner surface that defines an interior cavity. The interior cavity contains a tube that is in direct contact with the inner surface of the support structure. The tube has a wall that defines an internal opening with a sealed end. During the drawing process, the pressure of the internal cavity is regulated to a predetermined pressure.

• The patent application describes a method for manufacturing optical fibers.
• The method involves drawing the fiber from a hollow-core preform.
• The preform consists of an annular support structure with an inner surface and an interior cavity.
• The interior cavity contains a tube that is in direct contact with the inner surface of the support structure.
