Description

Electro-optic modulator

Technical Field

Background

Fiber optic communications is one of the main support posts for modern communications. With the explosion growth of data communication services, the requirements on the communication bandwidth are increasing, and the single-wavelength bandwidth of the current optical fiber communication system is advancing from 2.5Gb/s and 10Gb/s to higher bandwidths. Information is loaded onto the laser light into an inner modulation and an outer modulation. The physical basis of the electro-optic internal modulation and the external modulation is the electro-optic effect, namely that the refractive index of certain crystals changes under the action of an external electric field, and when light waves pass through the medium, the transmission characteristics of the light waves are influenced and changed. The modulation crystal is a core component of the electro-optic modulator, is processed into a cylinder or a rectangular body according to a certain direction, and is arranged in a container electro-optic modulator body to form the electro-optic modulator.

Most of the existing electro-optical modulators are connected with optical fibers for optical fiber communication systems, but the materials of the inner cores of the optical fibers are all glass materials and cannot be bent at a large angle, so that the optical fibers connected with the electro-optical modulators need to be protected. In view of this, we propose an electro-optic modulator.
