Propagation Speed of Electromagnetic Waves01:30

Propagation Speed of Electromagnetic Waves

Electromagnetic waves are consistent with Ampere's law. Assuming there is no conduction current Ampere's law is given as:
Pilot and Numeric Relaying01:21

Pilot and Numeric Relaying

Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:
Time and frequency -Domain Interpretation of Phase-lag Control01:21

Time and frequency -Domain Interpretation of Phase-lag Control

Phase-lag controllers are widely used in control systems to improve stability and reduce steady-state errors. A dimmer switch controlling the brightness of a light bulb serves as a practical example of phase-lag control, gradually adjusting the bulb's brightness. Mathematically, phase-lag control or low-pass filtering is represented when the factor 'a' is less than 1.
Phase-lag controllers do not place a pole at zero, but instead influence the steady-state error by amplifying any finite,...

    Area of Science:

    • Optical networking
    • Telecommunications engineering
    • Integrated optics

    Background:

    • Optical packet switching (OPS) networks require precise timing for efficient data handling.
    • Existing synchronization methods can be complex or energy-intensive.
    • Self-synchronization schemes offer a potential solution for simplifying OPS node design.

    Purpose of the Study:

    • To develop and demonstrate a compact, all-optical self-synchronization scheme for optical packet switched network nodes.
    • To provide both packet clock signals and packet beginning marker pulses.
    • To evaluate the scheme's performance with various data packet types.

    Main Methods:

    • Utilized a circuit with two hybridly integrated Mach-Zehnder interferometer (MZI) switches.
    • Implemented an all-optical approach, eliminating the need for electronic conversions.
    • Tested the scheme with synchronous, asynchronous, and variable-length data packets.

    Main Results:

    • Successfully demonstrated an all-optical, self-synchronizing scheme.
    • The circuit reliably generated both packet clock and marker pulses.
    • Evaluated performance at a data rate of 10 Gb/s with diverse packet types.

    Conclusions:

    • The proposed scheme offers a compact and efficient solution for optical packet switched network synchronization.
    • It requires relatively low operating energies.
    • This all-optical approach simplifies OPS node architecture and enhances performance.
