Abstract

Embodiments of the present invention provide an optical isolation device and an optical isolation method. The optical isolation device of the present invention includes: a first polarization beam splitting converter, a second polarization beam splitting converter, and a TM mode optical isolator; the first polarization beam splitting converter is used to receive TE mode signal light, and convert the TE mode signal light It is the TM mode signal light, and transmits the TM mode signal light to the TM mode optical isolator; the TM mode optical isolator is used to receive the TM mode signal light from the first polarization beam splitting converter, and transmit the TM mode signal light to the second Two polarization beam splitting converters; the second polarization beam splitting converter is used to receive the TM mode signal light from the TM mode optical isolator, restore the TM mode signal light to the TE mode signal light, and convert the TE mode signal light from the second polarization output of the splitter converter. The embodiments of the present invention realize the light isolation of the TE mode, and the device size is small and the process is relatively simple.

Description

technical field [0001] Embodiments of the present invention relate to optical communication technology, and in particular to an optical isolation device and an optical isolation method. Background technique [0002] The basic working principle of an optical isolator is to allow light to pass in one direction and block light in the other direction. The function of the optical isolation device is to prevent reflected light from causing damage to active optical devices (such as lasers, etc.). At present, in the field of optical communication, there is no optical isolator for isolating light in a transverse electric (Transverse Electric, TE) mode. Contents of the invention [0003] Embodiments of the present invention provide an optical isolation device and an optical isolation method, so as to implement optical isolation of TE mode signal light. [0004] In the first aspect, an embodiment of the present invention provides an optical isolation device, including: [0005] Th...
