Problems solved by technology

These mechanisms are largely limited by the medium type, boundary conditions, refractive index distribution, etc., making the realization of all-optical optical path control more demanding.
Dimensionally, previously proposed mechanisms either only regulate in one dimension, or do not regulate separately and independently in two transverse dimensions

Embodiment 1

[0020] The two-dimensional independently and continuously adjustable all-optical optical path control method of the present invention comprises the following steps:

[0021] Step 1, generating a bundle of fundamental mode Gaussian beams and a bundle of (0,1) mode Laguerre Gaussian beams with the same polarization, same frequency, and same transmission direction;

[0022] Step 2, making the generated fundamental mode Gaussian beam and (0,1) mode Laguerre Gaussian beam concentrically and coherently superimposed on the incident surface of the nonlinear medium;

[0023] Step 3, by adjusting the ratio coefficient b and the phase difference δ of the two beams, respectively adjust the magnitude and direction of the center of gravity of the composite beam in the nonlinear medium from the initial position, thereby realizing two-dimensional independently and continuously adjustable plenoptic optical path control.

[0024] Its physical basis is the two-dimensional independent continuous ...

Abstract

The invention relates to the technical field of optics, and in particular relates to a two-dimensional independently and continuously adjusted all-optical path control method and device. The physicalbase in the invention is the two-dimensional independently and continuously adjusted transverse momentum in a composite beam; a base mode Gaussian beam and a modular laguerre Gaussian beam (0, 1), which are same in polarization, frequency and transmission direction, are concentrically and coherently stacked on the incidence plane of a nonlinear medium, so that the composite beam is formed; when transmission is carried out in the nonlinear medium, the size and the direction, in which the gravity centre of the composite beam deviates from the initial position, can be adjusted independently and continuously through the proportional coefficient b and the phase difference delta of two combined light respectively; and thus, two-dimensional independently and continuously adjusted all-optical pathcontrol can be realized. By means of the two-dimensional independently and continuously adjusted all-optical path control method and device in the invention, independent and continuous adjustment onoptical path deviation can be conveniently carried out in the two dimensions including the size and the direction.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a two-dimensional independently and continuously adjustable all-optical optical path control method and a device thereof. Background technique [0002] All-optical optical path control has important applications in all-optical information processing fields such as optical routing, optical switches, and optical logic gates. Therefore, researchers are devoting themselves to the development of various all-optical optical path control techniques. Unlike electrons, photons cannot directly interact with each other, and can only indirectly realize the interaction between light and light through nonlinear optical effects and other means. In the past, some mechanisms of plenoptic optical path control have been discovered, such as soliton interaction, boundary lateral confinement, linear refractive index distribution and nonlinear response interaction, etc. These mechanisms are largely ...
