Performance effect in optical-communication systems caused by phase ripples of dispersive components

Area of Science:

• Optical Engineering
• Signal Processing
• Photonics

Background:

• Optical components are susceptible to performance degradation from phase ripple.
• Accurate modeling of phase ripple effects is essential for high-speed optical communication systems.

Purpose of the Study:

• To develop a simplified theoretical framework relating optical component performance to phase ripple characteristics.
• To validate the proposed theory using simulations and experimental data for chirped fiber gratings.

Main Methods:

• Formulating a theory that correlates component performance with the spectrum-weighted variance of phase ripple amplitude.
• Conducting 10-Gbit/s test-bed simulations of chirped fiber gratings.
• Comparing theoretical predictions with simulation and experimental measurement results.

Main Results:

• The developed theory provides a direct relationship between phase ripple variance and optical component performance.
• Model predictions show strong agreement with 10-Gbit/s test-bed simulations for chirped fiber gratings.
• Experimental measurements confirm the validity of the theoretical model.

Conclusions:

• The simple theory effectively quantifies the impact of phase ripple on optical component performance.
• The validated model is applicable to the design and analysis of high-speed optical communication devices like chirped fiber gratings.
