This study presents a novel method for automatically generating flat-top electro-optic frequency combs (EOFCs). The technique uses cascaded modulators and particle swarm optimization for efficient, self-starting comb generation.

Area of Science:

Photonics
Optical Engineering
Signal Processing

Background:

Electro-optic frequency combs (EOFCs) are crucial for various applications.
Traditional EOFC generation often requires complex, manual optimization.
Achieving flat-top spectral profiles is essential for high-performance applications.

Purpose of the Study:

To develop an automated method for generating flat-top EOFCs.
To enable photonic sampling of microwave signals using the generated EOFCs.
To simplify the optimization process for EOFC generation.

Main Methods:

Utilizing cascaded Mach-Zehnder modulators (MZM) and phase modulators (PMs).
Employing photonic sampling of dual single-tone microwave signals for feedback.
