Home / Calculation of polarization stride length of polarization-maintaining fiber
The polarization beat length ( L_b ) can be calculated using the formula: ( L_b = frac {lambda_0} {n_x – n_y} ) where ( lambda_0 ) is the vacuum wavelength, and ( n_x ) and ( n_y ) are the refractive indices for the two orthogonal polarization states. Polarization-maintaining fibers can have polarization beat lengths of a few centimeters or even only a few millimeters. This is a much stronger birefringence than achievable by strongly bending a fiber with radially symmetric.
