We developed a novel bidirectional optical add-drop multiplexer for single-fiber networks. This device efficiently adds/drops channels in both directions, achieving over 16 dB gain and reducing unwanted light reflections.

Area of Science:

  • Optoelectronics
  • Optical Communications
  • Photonics

Background:

  • Single-fiber bidirectional networks offer spectral efficiency.
  • Existing optical add-drop multiplexers face challenges in bidirectional signal handling and noise reduction.

Purpose of the Study:

  • To propose and demonstrate a novel bidirectional optical add-drop multiplexer (OADM).
  • To enable efficient channel addition and dropping in both directions within a single fiber.

Main Methods:

  • Utilized multiport circulators, fiber-Bragg gratings, and a single amplifier.
  • Incorporated Bragg gratings and a light absorber to mitigate Rayleigh backscattering and reflections.

Main Results:

  • Achieved bidirectional gain exceeding 16 dB.
