  • Publication number: 20240048243
    Abstract: Apparatus including an optical signal generator, a data transmission path, and an optical signal receiver. Optical signal generator includes a coherent light source for generating a spectrum of carrier signals at different carrier frequencies, an optical demultiplexer that receives and separates the different carrier signals into separate optical paths, a pair of optical modulators located in each of the separate optical paths to modulate each different carrier signal with a data signal and produce an upper and lower sideband pair at each of the different carrier frequencies, and an optical interleaver to combine the upper and lower sideband pairs into an optical super-channel of interleaved sub-bands. Optical signal receiver includes a demodulator for extracting the data signals. Optical modulators are configured to reuse each carrier signal to transmit different data in each of the upper sideband and the lower sideband and increase the capacity of the super-channel. Also a method.

  • Patent number: 9042685
    Abstract: This invention concerns real-time multi-impairment signal performance monitoring. In particular it concerns an optical device, for instance a monolithic integrated photonics chip, comprising a waveguide having an input region to receive a signal for characterization, and a narrow band CW laser signal. A non-linear waveguide region to mix the two received signals. More than one output region, each equipped with bandpass filters that extract respective discrete frequency bands of the RF spectrum of the mixed signals. And, also comprising (slow) power detectors to output the extracted discrete frequency banded signals.
