ABSTRACT:
A method for the production of a thin film on an end surface of a fiber made up of a core of an organic material, and a clad made of glass. This method involves the steps of placing the fiber in a vacuum chamber, reducing the pressure in the chamber, cutting the fiber under reduced pressure, and either simultaneously, or immediately after cutting the fiber, forming a thin film on the cut surface of the fiber.
