Abstract

Possibilities of short light pulses forming using a controllable Fabry-Perot interferometer based on an optical fiber were considered. This controllable interferometer consists of four similar Bragg´s gratings which are set in a certain order on a fiber and which produce two interferometers. If the length of the first interferometer is 10m and the length of the second one is 67mm, gratings reflection for Bragg wavelength equal 0.99 and when the power of 100 W comes to such an interferometer in a fiber then it is possible to obtain 10⁶ W power pulses. Light pulses are formed due to reduction of gratings reflection to by electric field short pulse influence which is applied to the gratings by means of the value which is enough to produce the necessary change of optical fiber refraction index.
