Abstract: A DFB laser (2) is coupled to a monomode line fiber (14) via an isolator constituted by a Faraday rotator crystal (4) and a polarizing fiber (10) which is welded to a fiber to be coupled (14). A focusing lens (8) is integrated in an intermediate block including the rotator crystal (4) and a permanent magnet (6). The invention is particularly suitable for making light-emitting heads for use in optical fiber telecommunications systems.

Abstract: To increase the transmission length in an optical fiber, a method of transmitting digital data uses both power modulation and phase modulation of an optical carrier. To compensate the chromatic dispersion produced by the fiber, a phase-shift is applied to the wave within each time cell in which the optical power is low and that precedes or follows a cell in which the power is high. Applications include long-distance optical transmission using standard fibers.

Abstract: Multiple wavelength source, in particular for optical communication employing a plurality of wavelength multiplexed channels, comprising a broadband light source (2) coupled to a discrete wavelength separator (3). The wavelength separator means (3) compromises cascaded refractive Bragg gratings (14, 15, 16, 17) each reflecting a discrete wavelength (&lgr;n, . . . , &lgr;3, &lgr;2, &lgr;1) to a source output (20).

Abstract: The assembly is implemented in the form of an optical head integrating not only an optical isolator (6, 8), but also a semiconductor amplifier and phase modulator (18). The amplifier-modulator is aligned parallel to the light-emitting laser (2) by a rotation compensator (14, 15) that compensates for the rotation applied by the isolator to the polarization of light from the laser. The invention is particularly applicable to optical fiber telecommunications.
