Abstract

The invention discloses a compact-type polarization-maintaining three-port optical circulator. The compact-type polarization-maintaining three-port optical circulator comprises a double-polarization-maintaining fiber collimator, a circulator core and a single-polarization-maintaining fiber collimator which are sequentially arranged from left to right; the double-polarization-maintaining fiber collimator comprises a first polarization-maintaining optical fiber, a third polarization-maintaining optical fiber, a double-fiber thin tube, a first collimating lens and a first fixed glass tube; the circulator core comprises a permanent magnetic ring and further comprises a Wollaston prism, a Faraday rotary optical plate and a polarizing film, and the Wollaston prism, the Faraday rotary optical plate and the polarizing film are sequentially fixed in the permanent magnetic ring from left to right; the single polarization-maintaining fiber collimator comprises a second polarization-maintaining optical fiber, a single-fiber thin tube, a second collimating lens and a second fixed glass tube. The compact-type polarization-maintaining three-port optical circulator is compact in structure, small in size, simple in manufacturing technology, low in assembling difficulty, low in cost and excellent in performance.

Description

technical field [0001] The invention relates to the field of optical fiber communication, in particular to an optical circulator. Background technique [0002] As the application of optical fiber communication and optical fiber sensing in the fields of telecommunications, aerospace, navigation and industrial manufacturing becomes more and more common, the demand for various optical devices of optical fiber communication system and optical fiber sensing system is also increasing. This demand not only increases the demand for the number of optical devices, but also has higher and higher requirements for the type, performance, volume and cost of the optical devices. [0003] In the fields of optical fiber communication and optical fiber sensing, the circulator is an important component in optical passive devices. The characteristics of being cut off and directed to other ports can realize the separation of forward and reverse optical signals. Therefore, circulators have been ...
