  • Method and system transmitting optical signals generated by multi-line sources via WDM optical network
    Patent number: 6607311
    Abstract: A transmission of optical signals generated by multi-line optical sources is provided via multichannel WDM optical network. Each multi-line optical source generates optical spectral lines within designated spectral range associated with the spectral window allocated for corresponding WDM channel, and comprises a plurality of spectral lines. Spectral lines are substantially narrower than the spectral separation between the lines.

  • Method and system for optical multichannel transmission using coherence division multiplexing with optical filtering
    Patent number: 6111679
    Abstract: A method and system of Coherence Division Multiplexing (CDM) for transmitting of a plurality of optical signals over the same optical fiber utilizing path-matched interferometry and phase modulation of partially coherent light, based on optical selecting and filtering of each CDM optical signal and reducing noise affiliated with other non-selected CDM optical signals.
