  • Patent number: 7035542
    Abstract: The present invention propose to use an optical multiplexer associated with an optical clock as a wavelength converter. Each RZ coded tributary will be carried by a single wavelength (channel) passively interleaved with the others without interferometric interaction hence achieving a not necessarily perfect OTDM. This input data stream as optical data signal composed of different wavelengths is then launched on at least one data access of said optical multiplexer used as a wavelength converter. An optical clock at the desired bit-rate is launched on the probe access of said optical multiplexer synchronously to the multi-wavelength data stream. At the output, the initial clock wavelength is converted on data signal using the gain conversion property of the optical multiplexer. In such a way, a data stream of substantially higher bit-rate is obtained while due to a very precise synchronization a lost of data is minimized.

  • Publication number: 20050201760
    Abstract: It is an object of the present invention to provide a method for processing optical signals and a transmitter for the signals adapted for ultra-high bit rate without implying obligatory a substantial increase in costs. This object is achieved by applying a method for processing optical signals to be transmitted through an optical transmission line using optical pulse stream with a carrier suppressed return to zero (CS-RZ) format to be obtained from at least an optical modulator. That method is characterized by driving the optical modulator with a combination of two sinusoidal electrical voltages, one at some frequency f and the second one at the third harmonic 3 f of such frequency.

  • Patent number: 6868102
    Abstract: The present invention provides a generator of a CS-RZ optical clock signal at a predetermined clock frequency. The generator contains a first laser source and a second laser source which respectively produce first and second continuous lightwaves, where the laser frequency of at least one of the sources is adjustable. The generator also contains a coupler disposed to receive the first and second lightwaves and forms optical beats at a beat frequency. An opto-electronic feedback is used to servo-control the adjustable-frequency laser source(s) in such a manner that the beat frequency, which is equal to the difference between the laser frequencies, is substantially equal to the clock frequency.

  • Patent number: 6674569
    Abstract: Known optical power equalizers receive an optical main input signal modulating between high and low input power levels. The optical power equalizers emit an equalized optical main output signal modulating between high and low output power levels, where at least one of the two sets of high and low power levels is equalized to one high or one low output power level. Such devices can comprise at least one gain-clamped semiconductor optical amplifier that operates about its saturation range. The optical power equalizer receives an amplifier input signal, which has one or more modulated portions, and emits a modulated amplifier output signal. According to the invention the dependence of the gain-clamped semiconductor optical amplifier's gain on the power of the amplifier input signal is adjusted such that the high input power levels of the amplifier input signal are equalized into the one high output power level of the amplifier output signal.

  • Patent number: 6611639
    Abstract: An optical module advantageously uses optical conversion fibers not only for a single channel but for sets of channels that are, in a specific way, selected from a multi-channel wave division multiplex (WDM) grid. The sets of channels are defined such that four wave mixing is negligible or has a negligible effect. The optical module has a demultiplexer, a multiplexer, and parallel optical conversion fiber portions that are arranged between the demultiplexer and the multiplexer. Each of the parallel optical conversion fiber portions has a specific dispersion map and transmits a different set of channels of the multi-channel WDM grid. These channels are regularly spaced from each other.

  • Patent number: 6424443
    Abstract: To resynchronize input optical signals with different optical carrier frequencies f1, f2 a delayed optical signal is created by applying a variable time-delay to one of the signals. A combination signal is formed by coupling measurement optical signals respectively obtained from the delayed signal and from the other input signal. A mixed signal is formed by injecting the combination signal into a non-linear optical device. A filtered signal is formed from the mixed signal using a filter tuned to an optical frequency f3 equal to p.f1+q.f2, p and q being relative integers such that the frequency f3 is different to the frequencies f1 and f2 of the carrier waves. The variable time-delay is controlled in accordance with a control electrical signal representative of the average value of the intensity of the filtered signal. Applications include wavelength-division multiplex optical communication systems.

  • Patent number: 6341022
    Abstract: The invention relates to an optical fiber transmission system using soliton signals with wavelength division multiplexing in which the wavelengths, &lgr;1 to &lgr;n, of the various channels of the multiplex are selected in such a manner that at least one point of the transmission system, the difference between the bit times of any two channels of the multiplex is substantially a submultiple T/N of the clock period. The invention proposes placing a synchronous modulator at said point to modulate the soliton signals at a frequency N/T which is a multiple of the soliton clock frequency 1/T. In a frequency allocation scheme that ensures that the bit times of the channels are synchronous at an interval ZR, this makes it possible to modulate all of the channels at intervals that are submultiples of ZR by using modulation frequencies that are multiples of the clock frequency.
