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 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: The device has an acoustic-optic material e.g. tellurium dioxide crystal, including one of prisms (P1, P2) and allowing acousto-optic interaction between an optical beam and an acoustic beam. An acoustic wave of the acoustic beam generates, in the prisms, an integrated deflective Bragg cell which diffracts, selectively in amplitude, wavelengths of the optical beam according to characteristics of the acoustic beam in order to generate non-diffracted optical waves and diffracted optical waves. The non-diffracted waves are programmed based on the optical wavelength by the interaction.

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
