This study introduces a silicon ring resonator for chirp-free optical modulation. The method enables both phase and intensity modulation by tuning the coupling coefficient, achieving efficient optical signal processing.

Area of Science:

  • Photonics
  • Optical Communications
  • Integrated Optics

Background:

  • Chirp-free optical modulation is crucial for high-speed data transmission.
  • Existing methods often face limitations in achieving both phase and intensity modulation without chirp.

Purpose of the Study:

  • To propose and validate a novel silicon ring-based optical modulation technique for chirp-free operations.
  • To demonstrate the capability of modulating both phase and intensity of light using a single silicon ring resonator.

Main Methods:

  • Utilizing a silicon ring resonator with a push-pull coupling structure to tune the coupling coefficient.
  • Operating the light at the resonance frequency of the ring.
  • Varying the coupling coefficient over large and small ranges to achieve phase and intensity modulation, respectively.
