Problems solved by technology

However, the light spot is small after the beam exits from the fiber optic head, but it will form a larger spot after passing through the self-focusing lens, so the Faraday rotator installed on the rear side of the self-focusing lens requires a large area
However, due to the high production cost of the Faraday rotator, such a design would result in a high production cost of the optical hybrid device

Description

technical field [0001] The invention relates to an optical device, in particular to an optoelectronic device with small volume and integrated optical isolation function. Background technique [0002] With the development of network communication, the data transmission speed of the optical fiber network is getting faster and faster, and the requirement for the capacity of the optical fiber network is also getting higher and higher. The existing optical fiber network transmission system uses a large number of various optical devices, such as isolators, optical splitters, depolarizers, etc. With the development of technology, various devices need to be used comprehensively to achieve the required functions. Therefore, the existing Fiber optic networks make extensive use of various optical hybrid devices. [0003] There are mainly two kinds of existing optical hybrid devices, one is a device in which optical fibers are arranged at both ends of the optical device, which is the m...
