. . . . . . . . results from a case of nonlinear dispersion compensation in which the nonlinear dispersion compensation in which the nonlinear chirp caused by self-phase modulation balances, postpones, the temporal broadening induced by group velocity delay.

Photonic crystal fibers also called as . . . . . . . .

A. Conventional fibers

B. Dotted fibers

C. Stripped fibers

D. Holey fibers

An optical fiber behaves as a birefringence medium due to differences in . . . . . . . .

A. Effective R-I and core geometry
