Embodiment Construction

[0028] As shown in Figures 1-4, a light beam enters the first rectangular prism RAP1 from the right, and then enters the polarizing beam splitter PBS. The polarization component parallel to the light incident plane is defined as S light, and the polarization component perpendicular to the light incident plane is defined as P light. In the polarizing beam splitter PBS, the S light is reflected and the P light is transmitted, forming two outgoing light rays whose polarization planes are perpendicular to each other. Using the second right-angle prism RAP2 and the polarization beam splitter PBS, two mutually perpendicular light rays enter the polarization rotation element PRE in parallel. The S light and the P light enter the third right-angle shuttle mirror RAP3 from the polarization rotation element PRE, pass through the polarization rotation element PRE in reverse, and finally enter the second right-angle prism RAP2 and the polarization beam splitter PBS.

[0029] When PRE is ...

Abstract

Reflective type magneto-optical switch, relates to a magneto-optical switche. With three right-angle prism, polarization beam splitter and polarization rotation device; First rectangular prism input external laser, then strikes into the polarization beam splitter; polarization beam splitter output will be 2 laser beam decomposition orthogonal polarization state S-P light and the second right-angle prism external input polarization beam splitter side, will be reflected to incident light polarization rotation device; polarization rotation of the input device proximal external polarization beam splitter and the second output Right-angle prism output, and output from the left will be part of the two polarized light beam strikes into a third rectangular prism; third rectangular prism external polarization rotation of the left part of the device output, and the third in the rectangular prism Polarized light reflection to the left part of the rotating device input port, the polarization rotation device, a bouquet of polarized light to the second right-angle prism, a reflection to the polarization beam splitter merger with another a bouquet of polarized light, and in accordance with the requirements of entry output ports.

Description

technical field [0001] The invention relates to a magneto-optical switch, in particular to a reflective magneto-optic switch. Background technique [0002] With the development of optical fiber communication technology and a large number of applications of DWDM, DWDM all-optical network is becoming the main development direction of communication network. The development of all-optical networks will depend on the progress of new-generation optical switches, wavelength division multiplexers, optical attenuators, and optical amplifiers. The optical switch is one of the core components of the all-optical network, and its performance directly affects the performance of the network. Optical switches have the characteristics of large-scale integration of devices, high coupling efficiency with optical fibers, large communication bandwidth, high reliability, and mass production, and have become one of the key technologies of all-optical networks. As one of the essential key compone...
