    This study demonstrates a novel all-optical delay line for synchronizing and time-multiplexing 10 Gb/s optical data packets. The system achieves rapid delay reconfiguration in under 300 ps.

    Area of Science:

    • Optical Communications
    • Photonics
    • Waveguide Technology

    Background:

    • High-speed optical data transmission requires precise synchronization and multiplexing of data packets.
    • All-optical signal processing offers advantages in speed and efficiency over electronic methods.
    • Tunable optical delay lines are crucial components for dynamic network management.

    Purpose of the Study:

    • To develop and characterize a tunable all-optical delay line for synchronizing and time-multiplexing 10 Gb/s non-return-to-zero (NRZ) on-off keyed (OOK) optical data packets.
    • To investigate the performance of wavelength conversion in periodically poled lithium niobate (PPLN) waveguides for optical delay.
    • To assess the effectiveness of dispersion compensation techniques for maintaining signal integrity.

    • Utilized a 26-ns tunable all-optical delay line.
    • Employed wavelength conversion in periodically poled lithium niobate (PPLN) waveguides.
    • Integrated inter-channel chromatic dispersion management using dispersion compensating fiber (DCF).
    • Implemented intra-channel dispersion compensation with a chirped fiber Bragg grating (FBG).

    Main Results:

    • Successfully synchronized and time-multiplexed 10 Gb/s NRZ-OOK optical data packets.
    • Achieved a tunable delay range of 26 ns.
    • Measured a delay reconfiguration time of less than 300 ps.
    • Demonstrated effective dispersion compensation for signal integrity.

    Conclusions:

    • The developed all-optical delay line is a viable solution for high-speed optical data packet synchronization and time-multiplexing.
    • The combination of PPLN wavelength conversion and advanced dispersion compensation enables efficient optical delay.
    • The rapid reconfiguration time makes this technology suitable for dynamic optical network applications.
