This novel method demonstrates high-speed polarization tracking in optical fiber communication, suggesting improved efficiency over traditional techniques.
A high-speed polarization tracking method for optical fiber communication systems is proposed, by reformulating polarization control as a multi-dimensional optimization problem and employing Adam optimization. The method achieves polarization tracking at Mrad/s speeds, overcoming over-convergence issues of gradient descent.
