Self-phase modulation of single-mode fiber
The singlemode waveguide structure maintains the spatial profile unaffected. Nonlinearity can be observed with picosecond pulses of only a few Watt of peak power. Kerr nonlinearity leads to the modulation of the temporal phase of a pulse propagating in a nonlinear waveguide :. Due to the Kerr effect, high optical intensity in a medium (e.
