Abstract

The invention provides a magneto-optical switch, which comprises a single-fiber collimator, a first birefringent crystal, a first slide group, a first Faraday rotator, a second birefringent crystal, a second Faraday rotator, a refracting prism, a second slide group, a third birefringent crystal and a double-fiber collimator, the single-fiber collimator and the double-fiber collimator are respectively used as a light path input end and a light path output end; a first birefringent crystal, a first slide set, a first Faraday rotator, a second birefringent crystal, a second Faraday rotator, a refracting prism, a second slide set and a third birefringent crystal are sequentially arranged between the light path input end and the light path output end in the light path transmission direction. The magneto-optical switch provided by the invention has two switch states, two different optical signal transmission paths can be generated by changing the positive and negative pole directions of external voltage, so that two state functions of 1 * 2 are realized, the optical transmission efficiency is high, and the magneto-optical switch is widely applied to the optical communication industry.

Description

technical field [0001] The invention relates to the technical field of optical components, in particular to a magneto-optical switch. Background technique [0002] The optical switch component is one of the important components of the all-optical network. In the optical fiber network system, the direct, cross or multi-party switching transmission of optical signals is very important in optical communication systems, sensing and detection fields, instrumentation fields, and defense industries. Wide range of applications. [0003] There are many ways to realize optical switches, including mechanical optical switches, microelectromechanical (MEMS) optical switches, electro-optical optical switches, thermo-optical optical switches, acousto-optic optical switches and magneto-optical optical switches. Both switching techniques have advantages and disadvantages. For example, mechanical optical switches can provide very small insertion power consumption and crosstalk characteristi...
