    Abstract: Un procédé de mesure par interférométrie utilisant de la lumière comprimée où une impulsion d'entrée est fractionnée en deux impulsions d'entrée consécutives (15a, 15b) séparées par un intervalle de temps qui est inférieur à l'inverse de la largeur spectrale de la dispersion de Brillouin d'onde acoustique guidée. Les deux impulsions sont ensuite encore fractionées (16) en une première paire (20a, 20b) et une seconde paire (22a, 22b) d'impulsions et on provoque leur propagation dans des directions opposées par une boucle d'interférométrie à fibre optique (18) pour les recombiner à la sortie de la boucle (16). On fait passer les impulsions recombinées dans un modulateur de phase pi (38) qui module une des deux impulsions. La sortie est alors introduite dans un détecteur équilibré (50) où on détermine la moyenne des deux signaux pour que le bruit de dispersion de Brillouin d'onde acousitique guidée soit éliminé.

    Abstract: Un gyroscope à résonateur annulaire passif se compose d'un chemin annulaire à guide d'ondes électromagnétique provoquant une rotation spécifiée de la polarisation des ondes, une fois pour chaque tour dans le chemin annulaire. Pour un chemin annulaire à fibre optique on introduit une fonction à un certain point dans ledit chemin annulaire, dans lequel les extrémités des fibres tournent les unes par rapport aux autres afin d'effectuer une rotation de polarisation.

    Abstract: A wavelength converter which employs an optical fiber and has high converter efficiency. The polarization planes of a signal light and an exciting light outputted from a laser diode (LD) (103) are respectively controlled by polarization controllers (PC's) (101 and 104) and the phases of the lights are respectively modulated by phase modulators (PM's) (102 and 105) in accordance with modulation signals outputted from an oscillator (110). Then, the output lights from the PM's (102 and 105) are multiplexed by a coupler (106). After the multiplexed signal light and exciting light are amplified by an optical amplifier (EDFA) (107), they are inputted to a dispersion shift fiber (DSP) (108). After wavelength transformation (four light waves mixing (FWM)) is practiced in the DSP, an FWM light is outputted through a band-pass filter (BPF) (109).
