Question

Could please write the information about non-Linear optics like definition for what it uses and the advantages and disadvantage??

Answer 1

The nonlinear optics is the field which includes all phenomena in which optical parameters of materials are changed with the interaction of intense coherent source of light. The nonlinear optical phenomenon leads to the enhancement of understanding light -matter interactions.

nonlinear effects can play useful and important roles in enhancing the fiber performances and creating new functions by way of fiber lasers, amplifiers, switches, logic devices, demultiplexers, signal format conversion and wavelength conversion devices.

Nonlinear effects in optical fibers impose different limitations on the communications link, and an understanding of such effects is almost a prerequisite for actual lightwave-system designers.
