摘要： The hydrophone has an interferometer structure incorporating a measuring arm in which is provided a very long monomodal optical fibre immersed in the interaction medium in which is propagated the acoustic wave. A phase displacement is induced on the optical wave by the elastooptical effect and said wave is propagated in the fibre by the acoustic wave which creates an acoustic pressure field in the medium. A reference arm establishes a reference optical path and the phase displacement linked with the acoustic wave is detected by interferometry between the two optical waves emerging from the two arms. The optical connections between the source, the optical fibre immersed in the interaction medium, the reference arm and the detector being provided in guided optics in a compact structure.

摘要： A Switch is disclosed which makes it possible to optically connect at least one of the circuits of a group of input circuits to at least one circuit of a group of output circuits. A photosensitive medium is illuminated by parallel beams from a matrix of input circuits which beams are then defracted on layers written in the medium and then reach one of the circuits of the matrix of photoreceiver circuits. The layers are written by interference of two beams whose wavelengths differ from that of input beams with the wavelength of the input beams being out of the spectral sensitivity range of the photosensitive medium.

摘要： The invention relates to a compact optical structure comprising a semiconductor emitter junction, a laser or a light emitting diode, coupled to a plane waveguide formed by a layer of photo-polymer deposited on a substrate with a suitable index. A surface layer, of photo-polymer for example, enables the registration of photo-induced diffraction structures performing particular optical functions such as that of a distributed reflector, deflector or lens. Such compact structures are applicable, in particular to the designing of simple, small devices, laser sources with distributed external resonators, interferometric gyrometers, hydrophones, multiplexers or demultiplexers.

摘要： The invention relates to a semiconductor laser with a distributed reflector comprising a semiconductor junction, one of whose semi-transparent mirrors is a split face of the semiconductor in which is integrated a light emitting junction with epitaxial layers. The active layer of this junction is coupled to a waveguide integrated in a dielectric medium, on one face of which is engraved a grating forming a distributed reflector playing the part of the second mirror. The reflector, when functioning according the second order of counter coupling emits a diffracted wave normal to the waveguide which can easily be coupled to an optical fiber.

摘要： A system comprising means for emitting an analysis beam and a recording beam, the two beams being deflected by common deflection means. The analysis beam scans the document carrying the image to be analyzed and a detecting photocell provides an electrical signal. The recording beam scans a liquid crystal cell, where it records the image in synchronism with analysis in dependence upon a modulation of the thermo-optical effects induced in the liquid crystal. This modulation is provided by the electrical signal.
