This study introduces a new method for generating optical single-sideband (OSSB) signals using semiconductor optical amplifiers (SOAs). The technique achieves high sideband suppression ratios, demonstrating effective OSSB signal generation even for carrier-suppressed signals.

Area of Science:

  • Photonics
  • Optical Communications
  • Semiconductor Devices

Background:

  • Optical single-sideband (OSSB) signal generation is crucial for advanced optical communication systems.
  • Existing methods for OSSB generation often face limitations in suppression ratio, power range, or wavelength span.
  • Semiconductor optical amplifiers (SOAs) offer potential for efficient optical signal processing.

Purpose of the Study:

  • To propose and experimentally verify an improved method for generating complete OSSB signals.
  • To leverage the self-modulation birefringence difference in SOAs for OSSB generation.
  • To achieve high sideband suppression ratios (SSRs) over a wide operational range.

Main Methods:

  • Utilizing the self-modulation birefringence difference within a semiconductor optical amplifier (SOA).
