Summary
We developed a novel polarization-mode dispersion (PMD) compensator using a Michelson interferometer. This device effectively compensates for PMD, demonstrating significant potential for optical fiber communication systems.
Area of Science:
- Optical Engineering

- Effective PMD compensation is crucial for maintaining signal integrity and enabling higher data rates.
Purpose of the Study:
- To propose and experimentally validate a novel Michelson-interferometer-based polarization-mode dispersion (PMD) compensator.
- To demonstrate the PMD compensation capabilities of the proposed device using fiber optic components.
Main Methods:
- Design of a Michelson-interferometer-type PMD compensator incorporating a polarization beam splitter and quarter-wave plates.
- Experimental setup utilizing fiber devices to implement and test the proposed compensator.
- Evaluation of PMD compensation performance using the fixed-analyzer method.
Main Results:
- Successful experimental demonstration of the proposed Michelson-interferometer-type PMD compensator.
- Quantification of the PMD compensation ability, achieving 104 picoseconds (ps) using the fixed-analyzer method.
Conclusions:
- The proposed Michelson-interferometer-type PMD compensator is effective in mitigating polarization-mode dispersion.
