Click the “Birefringence” icon in the “Navigator” pane. The “Birefringence” dialog box
appears.

Optical Fiber - Birefringence

StepAction
1In the “Birefringence” dialog box, check the “Induced by Perturbation Parameters” option. The “Photoelastic Constants” entries become available.
2In the “Photoelastic Constants” section, enter: Young Modulus 7750000000, C 3.44e-011, Poisson Ratio 0.164.
3In the “Induced by Perturbation” Parameters section, check “Extrinsic”, “Bending”, and “Fiber Spooled With Tension”.
4Enter the “Bending” value 0.12
5Enter the “Fiber Spooled with Tension” value 0.5.
6In the “Output” section, enter “Spectral Range” 0.4 and “Number of Steps” 51.
7Press OK to close the “Birefringence” dialog box
8Go to the “Birefringence” view tab. The birefringence and Differential Group Delay (DGD) vs. wavelength are plotted there.

Your “Birefringence” view tab should look like this:

The results can now verified by selecting the “Birefringence” tab on the “Views”
window:
