Here is how the Modal Birefringence Degree equation looks like.

1E-7 = mod \underset{̲}{u} s (2.4E-7 - 1.4E-7)

1E-7 = mod \underset{̲}{u} s (2.4E-7 - 1.4E-7)

1E-7 = mod \underset{̲}{u} s (2.4E-7 - 1.4E-7)

How to Evaluate Modal Birefringence Degree?

Modal Birefringence Degree evaluator uses Modal Birefringence Degree = modulus(Mode Index X-Mode Index Y) to evaluate the Modal Birefringence Degree, Modal Birefringence Degree is a measure of the birefringence (difference in refractive indices for two orthogonal polarizations) associated with the optical modes supported in a waveguide or an optical fiber. It quantifies the extent to which different modes experience birefringence in the optical system. Modal Birefringence Degree is denoted by B_m symbol.
