Hi Aasif,
the last technique for dispersion compensation is “OPC, also called as the optical phase conjugationor midspan spectral inversion where the rays retrace the same path as they travelled upto the OPC…in other words the phaseis 180 shifted..
HOLEY FIBER
also called photonic crytal fibers and is emerging technology in terms of dispersion compensation.”
I am not aware of this technique, So please I need some more explanation, If possible refer a research paper implementing this technique. Thanking you.

Dhiman
