Chromatic dispersion effects in analog polarization-modulated links.

Area of Science:

• Optics and Photonics
• Telecommunications Engineering

Background:

• Photonic links are crucial for high-speed data transmission.
• Polarization modulation is a technique used in photonic links.
• Chromatic dispersion can degrade signal quality in optical systems.

Purpose of the Study:

• To analytically and experimentally investigate the impact of chromatic dispersion.
• To understand how dispersion affects photonic links with polarization modulation.
• To determine the influence of receiver design on dispersion-limited bandwidth.

Main Methods:

• Analytical study of chromatic dispersion effects.
• Experimental validation of theoretical findings.
• Analysis of polarization modulation in optical links.

Main Results:

• Dispersion induces a frequency-dependent rotation in analog polarization modulation.
• The orientation of modulation rotates around the center of modulation.
• The extent of rotation is dependent on signal frequency.

Conclusions:
