Abstract

The invention belongs to the technical field of optoelectronic communication, and more particularly relates to a space light adaptive coupling device based on crystal electro-optic effect. It includes a self-focusing lens, a support platform and a trapezoidal optical fiber. The core diameter of the trapezoidal optical fiber decreases from the front section to the tail section. The trapezoidal optical fiber includes at least three sections of optical fiber, wherein the front section is a multimode fiber, and the tail section is a single-mode fiber. The front end of the optical fiber is located at the focal point of the self-focusing lens, and the trapezoidal optical fiber is arranged on a supporting platform. The device has the characteristics of automatic response and dynamic adjustment, and can adjust the potential distribution according to the coupling efficiency, thereby changing the focusing constant and focal length of the self-focusing lens, realizing the optimization of the device structure, and ensuring efficient coupling of space light to single-mode fiber. In addition, because the device is easy to control, has no mechanical structure and has a high degree of integration, the device has higher application value.

Description

technical field [0001] The invention belongs to the technical field of optoelectronic communication, and more particularly relates to a space light adaptive coupling device based on crystal electro-optic effect. Background technique [0002] The electro-optic effect of a crystal refers to an effect in which the optical refractive index of a crystal changes due to an external electric field. When the refractive index varies linearly with an applied electric field, the effect is called the linear electro-optic effect. For LiNbO 3 For crystals, when the direction of the applied electric field is along the Z direction of the crystal optical axis, the direction of the main axis does not change and the refractive index in each direction is related to the strength of the applied electric field. [0003] A self-focusing lens means that the refractive index of the medium gradually changes along the radial direction according to a certain rule, and the refractive index distribution ...
