Abstract
Disclosed is a device for adjustable chirping in-fiber Bragg gratings comprising a straight beam of a longitudinally uniform cross-section, uniformly bent by an external force in a vertical plane including the axis of the beam, and an optical fiber provided with grating of uniform interval, or those having been chirped in advance at a predetermined rate of interval change, extending straight along said vertical plane in the beam when the beam is not loaded with the external force, from the top surface at one end to the bottom surface at the other end of the beam, penetrating on its way the neutral surface of the beam.
