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

Optical Fiber - Birefringence

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