Two laser beams interaction in photonic crystal fibers infiltrated with highly nonlinear materials

Abstract

In this letter, the results of experimental tests on the discrete light propagation in photonic liquid crystal fibers (PLCFs) are presented. More precisely, this work is mainly inquiring into the matter how two laser beams simultaneously launched into PLCF can influence the optical properties of the fiber. For this purpose, a weak collinear probe beam at the different wavelength has been applied to monitor how the waveguide channel(s) is (are) decoupled from the rest of the matrix due to the influence of the pump laser beam. Firstly, low-power signal beam at the wavelength of 532nm has been co-launched axially with the pump beam (1064nm) to confirm a power-dependence of optical properties (induced by the pump) while observing the signal beam profile at the output facet of PLCF. Secondly, the beams from the same laser sources in the inverted configuration have been applied.
