Zusammenfassung: | The present invention relates to a method and apparatus for tuning an optical fiber based optical device. An optical fiber device in accordance with the present invention is held at a first tension, and in accordance with the method of the present invention, heat is applied to the fiber to cause a release of tension. This can be used effectively to provide accurately tuned in-fiber Bragg gratings, or to trim fiber based interferometers. Advantageously, tuning method is significantly simplified over prior art methods. A further advantage is realized in that multiple fiber Bragg gratings can be packaged together and tuned separately, including multiple fibers or multiple gratings in a single fiber. |
