METHOD AND PULSE LIGHT SOURCE FOR GENERATING SOLITON LIGHT PULSE

摘要

PROBLEM TO BE SOLVED: To provide a method for generating soliton light pulses by using an optical waveguide with nonlinear optical properties.;SOLUTION: In the method for generating soliton light pulses, pump laser pulses are supplied by a pump laser source 10 and are coupled into a pulse guiding medium 20 having an anomalous group-velocity dispersion and a Kerr nonlinearity and are made to propagate along the pulse guiding medium, and soliton-shaped light pulses are formed from the pump laser pulses within the pulse guiding medium, and photoionization of the pulse guiding medium due to the soliton-shaped light pulses results in a frequency shift of the soliton-shaped light pulses toward higher spectral energy. In this method, the pump laser source and the pulse guiding medium are so set that the soliton-shaped light pulses propagate in the pulse guiding medium to become fundamental soliton light pulses 2 having sufficient intensity for inducing the photoionization.;COPYRIGHT: (C)2015,JPO&INPIT
