The invention provides an optical fiber, a method for the preparation thereof, and a device. An optical fiber, wherein a distal end of the optical fiber is provided with an optical mask adapted for projecting a predetermined pattern on a target surface by radiation transmitted from the distal end of the optical fiber, allows for the rapid application of patterns and three-dimensional structures on target surfaces, in particular on the ends of optical fibers.

Optical fiber, method of preparation thereof and device

A description is given of a switching device (1) comprising a transparent substrate (3), a reflective switching film (5) of yttrium having a thickness of 500 nm and a palladium layer (7) having a thickness of 5 nm. Using hydrogen gas at atmospheric pressure and at room temperature, a transparent, semiconductive film (5) of YH.sub.3 is formed, which is converted to a metallic mirror-like film (5) of YH.sub.2 by exposure to heat. The conversion of YH.sub.2 into YH.sub.3 is reversible and can for example be used in an optical switching element and in thin displays.
