摘要： A link using spectrum multiplexing, in which link an amplifying fiber amplifies a plurality of multiplexed carrier waves. The invention makes it possible to maintain a flat spectrum distribution of the gain of the amplifying fiber when the number of carrier waves varies. For that purpose, light that is amplified by the amplifying fiber and that is independent of the carrier waves is servo-controlled in power. The light is constituted by a reverse amplified spontaneous emission. After being filtered in a filter and detected by a photodiode, the light controls the power supplied to two laser diodes for pumping the fiber. The invention applies in particular to implementing optical transmission networks.

摘要： A method of manufacturing a multi-core optical fiber, the method including assembling together a plurality of substantially identical single-core optical fiber preforms (2', 2"), referred to as "single-core preforms", each of which includes a core bar (3) surrounded by a layer of optical cladding (4), so as to form a "multi-core preform" (10) and drawing down the multi-core preform (10) so as to obtain the multi-core optical fiber. The assembly step includes securing the single-core preforms (2', 2") to one another by fusing them over their entire lengths or over portions thereof along their tangential lines of contact (T), without inserting the multi-core preform (10) into a holding tube. A vacuum is maintained in the preform during the drawing step, the vacuum being formed before or during the drawing step.

摘要： A system for writing a Bragg grating point-by-point in an optical waveguide includes an illumination system for producing a primary beam. It further includes a diffraction grating to receive the primary beam and to produce a zero order secondary beam and two symmetrical secondary beams of higher order and a focusing optical device for focusing the secondary beams onto a writing area of the waveguide. The diffraction grating and the focusing optical device define an intensity function of writing in the area of the guide including a central peak and two secondary peaks spaced from the central peak by a distance equal to the pitch of the grating.

摘要： The source includes an electro-absorption modulator receiving a continuous light wave supplied by a laser emitter 10. The characteristic response curve of the modulator has a threshold so that the modulator transmits an optical pulse having a duration which is less than the duration of an electrical control pulse which is applied to the modulator by a control generator. Soliton-type optical pulses obtained in this way are transmitted via a line fiber to a receiver. Application to optical transmission.

摘要： A photodiode (26) receives an optical input signal (P1) and an internal optical signal (P2) and supplies in response thereto an internal electrical signal (I2), which in turn controls a laser (4) which effects amplification and supplies the internal optical signal and an output signal (P3). The feedback loop formed by this photodiode and laser leads to a strong non-linearity in the variation of the output signal as a function of the input signal. The invention is useful especially in optical fiber telecommunications systems.

摘要： A femtosecond dye laser comprises a dye amplifier assembly (30) pumped by a mode-locked neodymium YAG laser (35) operating with frequency doubling. The main dye laser cavity as defined on one side of the amplifier assembly (30) by a linear prism structure (11 and 14) leading to an outlet mirror (15), and on the other side of the amplifier assembly by an assembly (20) constituting an anti-resonant mirror disposed about a saturable absorption device (40). An error signal is tapped by leakage from one of the mirrors (22) and is spectrally analyzed and compared with a reference wavelength (at 50) enabling a high tension amplifier (60) to be controlled to act on a piezo-electric stack (19) in order to fix the position of the outlet mirror (15) so as to adjust the optical length of the cavity as a function of the spectral characteristics of the pulses it produces.
