Abstract: Optical, opto-electronic or photonic component comprising, for a given operating wavelength, at least one optical cavity defined between two reflectors and confined laterally. The reflectors are of the phase change type and the area between the reflectors that corresponds to the optical cavity has a cut-off wavelength greater than the cut-off wavelength of the area surrounding it laterally, the operating wavelength lying between the two cut-off wavelengths. The method enables manufacture of a component of this kind using relatively shallow etching.

Abstract: The method of transmitting a sequence of binary-coded information modulates the phase and the polarization of soliton pulses in such a manner that phase alternates between pairs of successive pulses, and the absolute value of the phase angle difference between two successive soliton pulses remains constant over the entire pulse train. The pulse train is transmitted by applying the method. Emission and reception apparatuses implement the method. The method is applicable to transmitting information over long distances.

Abstract: An optical transmission method and system for sending at least one stream of solitons over very long distances. The stream of solitons is stabilized by introducing repulsive interactions between each soliton and the immediately preceding soliton and immediately following soliton. This stabilization is affected by optical phase modulation of the solitons producing an alternation of radians in the relative phases between consecutive solitons. The information is coded by polarization modulation. The invention is useful in many industries such as the telecommunications industry.
