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:

Area of Science:

  • Photonics and Optical Communications
  • Integrated Optics
  • Semiconductor Devices

Background:

  • Non-return-to-zero differential phase-shift keying (NRZ DPSK) is a robust modulation format for optical communication systems.
  • Silicon microring resonators offer potential for miniaturized and energy-efficient photonic integrated circuits.
  • Existing DPSK demodulation often relies on bulky or complex interferometric structures.

Purpose of the Study:

  • To propose and analyze an ultra-small silicon-based microring resonator for both generating and demodulating NRZ DPSK signals at 10 Gb/s.
  • To investigate the performance dependencies of the microring modulator and demodulator under various operating conditions.
  • To compare the transmission performance of the all-microring-based DPSK transceiver with conventional Mach-Zehnder and delay-line interferometer approaches.

Main Methods:

  • Design and simulation of a silicon microring resonator modulator and filter.
  • Analysis of performance metrics including eye-opening, signal-to-noise ratio, and bit error rate.
  • System-level transmission experiments over 70-km single-mode fiber.
  • Parameter sweep studies for laser linewidth, phase shift, demodulator offset, and receiver bandwidth.

Main Results:

  • Demonstrated generation and demodulation of 10 Gb/s NRZ DPSK using a single silicon microring device.
  • Identified key operating parameters influencing transceiver performance.
  • Achieved an eye-opening improvement of up to 7 dB through optimization.
  • Showcased comparable or improved transmission performance over 70-km SMF compared to traditional DPSK systems.

Conclusions:

  • The proposed silicon microring resonator is a viable building block for compact and efficient DPSK transceivers.
  • Performance optimization of the microring-based DPSK system can significantly enhance data quality.
  • This technology offers a promising pathway towards highly integrated and cost-effective optical communication modules.
