Abstract: The method involves decomposing an ultra-brief light pulse (Ii) into pulses respectively denominating a signal pulse (Is) and a primary reference pulse (Irp), of different polarization or direction of propagation, where phase characteristics of the pulses are identical to the light pulse. Interaction is carried out between the primary pulse and a non-linear optical material (DMNL) to generate a secondary reference pulse (Irs). Spectral or spatial interferometric measurement is carried out by recombining the secondary pulse and the signal pulse with given or null time and angular offsets. An independent claim is also included for a device for measuring a spectral phase or combined spectral and spatial phase of an ultra-brief light pulse.

Abstract: Le procédé et le dispositif pour la mesure de la phase spectrale ou de phases spectrale et spatiale combinées d'impulsions lumineuses ultra brèves, consistent à effectuer :- une décomposition (S) de l'impulsion lumineuse (Ii) à mesurer en deux répliques identiques dénommées respectivement impulsion signal (Is) et impulsion de référence primaire (Irp), de polarisation ou de direction différentes et dont les caractéristiques de phase sont essentiellement identiques à l'impulsion d'origine (Ii),- un filtrage temporel (DMNL) de l'impulsion de référence primaire (Irp) par une interaction non linéaire générant une impulsion de référence secondaire (Irs) de fréquence moyenne essentiellement identique et de largeur spectrale supérieure à la largeur spectrale de l'impulsion de référence primaire (Irp),- une mesure d'interférométrie spectrale (SPEC) par recombinaison (R) de cette impulsion de référence secondaire (Irs) et de l'impulsion signal (Is) avec un décalage temporel donné.

Abstract: The invention concerns a device comprising a birefringent elasto-optic medium (1) equipped with a transducer (5) generating in the medium (1) a modulated acoustic wave along a specific direction, and means for coupling in the medium (1) an input optical wave with unknown polarisation, and a programming circuit for (amplitude-phase-frequency) modulation of the acoustic wave. Said device supplies a direct wave and two perpendicular diffracted waves of H, V polarisation each bearing a modulation based on the input optical wave modulation and the acoustic wave modulation.

Abstract: The invention relates to a programmable acousto-optical device in which an unknown input polarisation wave interacts successively with several different sound beams which are generated by piezoelectric transducers (T1 to T6) in one or more birefringent elasto-optical media. Said device comprises circuits for generating programmable discrete amplitude frequencies that are applied to the transducers (T1 to T6) and provides an output optical wave having a frequency spectrum amplitude modulation that is a function of both the input optical wave modulation and the sound wave modulation. The invention is particularly suitable for wavelength-multiplexed optical communication systems

Abstract: The acousto-optic device comprises a birefringent elasto-optic medium (1) equipped with a transducer (5). The transducer generates a modulated acoustic wave which interacts with an incident optical wave. The acousto-optic device comprises a birefringent elasto-optic medium (1) equipped with a transducer (5). The transducer generates in the medium (1) a modulated acoustic wave along a specific direction. Within the medium an input optical wave with unknown polarisation is coupled with the device. A programming circuit provides amplitude-phase-frequency modulation of the acoustic wave. The device provides a direct wave and two perpendicular diffracted waves of H,V polarisation, each bearing a modulation based on the input optical wave modulation and the acoustic wave modulation.
