    摘要： The invention relates to a semiconductor optical reflector serving in particular for being disposed facing an integrated laser cavity so as to feed light back into said cavity, and enable it to oscillate continuously. The reflector is made up of a plurality of cascaded Bragg reflector sections. More particularly, said sections are of the same length L and have the same coupling coefficient, and the length L of each pair of sections is given by the following relationship:L=.lambda..sup.2 /[(n.sub.i+1 +n.sub.i).times.1.7(n.sub.i+1 .LAMBDA..sub.i+1 -n.sub.i .LAMBDA..sub.i)]where .lambda. is the mean value of the Bragg wavelengths reflected by the reflector;n.sub.i+1 and n.sub.i are the respective effective refractive indices of said adjacent sections; and.LAMBDA..sub.i+1 and .LAMBDA..sub.i are the respective periods of said adjacent sections.The reflector of the invention has a wide spectrum band independent of the value of the coupling coefficient.

    摘要： The transmission system is suitable for amplitude modulated controlled phase optical signals (S) having an optical phase in each low level pulse that precedes or follows a high level pulse. The system includes an optical link (L) and, to allow a high transmitting power, optical corrector means (FG) are provided for applying optical filtering to the signal R at the exit (B) of the link and/or at one point or a plurality of points of the link (L), to compensate widening of its spectrum that the controlled phase signal (S) may suffer because of phase self-modulation during its transmission. Application to long-haul optical transmission.

    摘要： An optical modulation scheme for transmitting data over a fiber optic transmission line is proposed where the following steps are realized: creating a NRZ signal by amplitude modulation, modulating two branches of a interferometer structure by complementary electrical signals, and shifting one of the electrical signals against the other electrical signal in time. Further, an optical transmitter is proposed which can modulate the light in the new proposed modulation scheme.

    摘要： The invention describes a transmission system with transmitter, transmission line and receiver, where the transmitted signal is modulated by a diffential phase shift keying modulation scheme. This is realized in a differential coder and a phase modulator. The diffential coder comprises an EXOR circuit, with a time delay of at least 2 bit in the attached feed back loop.

    摘要： The demultiplexer comprises a diffraction space defined by a reception surface coupled to a grating. In order to obtain output waves of flattened spectral response, the input waveguide and the reception surface are dimensioned so that the input wave diffracts over said surface and presents a plurality of secondary lobes. The demultiplexer is particularly applicable to optical communications systems with wavelength multiplexing.
