ABSTRACT:
A non-linear optical fiber receives two light waves by its two ends, each light wave being modulated by means of two modulators. These light waves create photoinduced index variations in the fiber which are proportional to the intensity of the optical field. A reading source emits a reading wave in the fiber. This reading wave is reflected at least partially by the index variation or variations. A detector receives the reflected wave and makes it possible, through the computation of the returning time of the wave, to determine the position of the index variations. Applications: very wide passband signal correlators.
