Abstract

The invention provides a photoelectronic device. The photoelectronic device comprises an optical fiber head. Three optical fibers are arranged in the optical fiber head, and extend to the outside of the first end of the optical fiber head. An analyzing crystal is arranged at the second end of the optical fiber head. A half wave plate is arranged on one side, away from the optical fiber head, of the analyzing crystal. A focusing optical rotation component is arranged on one side of the second end of the optical fiber head, and comprises a self-focusing lens and a Faraday optical rotation device. A first reflecting and transmitting film is arranged on one side, away from the optical fiber head, of the focusing optical rotation component. The reflectivity of the first reflecting and transmitting film is much smaller than the transmittivity thereof. A wedge angle sheet is arranged on one side, away from the optical fiber head, of the focusing optical rotation component. A photoelectronic converter is arranged on one side, away from the focusing optical rotation component, of the wedge angle sheet. A second reflecting and transmitting film is arranged on one side, close to the focusingoptical rotation component, of the wedge angle sheet. The reflectivity of the second reflecting and transmitting film is much larger than the transmittivity thereof. The photoelectronic device has theadvantages that miniaturization of an optical mixing device can be realized, and the optical mixing device can have optical isolation and photoelectronic detection functions.

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] Existing optical hybrid devices are mainly devices with optical fibers at both ends. This is the most common optical device. The total length of this optical hybrid d...
