Dear Paul,

 

Thank you very much. I will include your comments into the minutes.

 

Best regards,

Yu,
I would like to offer a couple suggestions to improve the minutes.

Please change the following statement:
7.        In manufacture process, fiber is rotated when it is drawn, making the core symmetric. However, the platform may not be perfect straight, which cause the asymmetric of the fiber. This can be process dependent. The specified core no-circularity is less than 6% for 50 ìm fiber
to:
7.  In fiber manufacturing, the preform is rotated during glass deposition. However, the target rod or preform tube may not be perfectly round or straight which can lead to core asymmetry.  The magnitude may be process dependent, but the standardized limit for core non-circularity for 50 and 62.5 um core diameter MMFs is 6%.

Also, please clarify the following:
Opinion 2: Due to the symmetric of the fiber, the power excited in each mode is independent of the polarization variation of input beam.
I think what is meant is:
Opinion 2:  For circularly symmetric fibers, the power excited in each mode group is independent of the input polarization state and excitation position.  Only asymmetry in the core can cause such dependancies.
