Abstract

The invention provides an electric polarization controller automatic debugging device which comprises a polarization beam splitter, a power supply, a core board, a semiconductor laser module, a debugged electric polarization controller, a high-voltage delay circuit, a first light intensity measurement module and a second light intensity measurement module. The semiconductor laser module is connected to the debugged electric polarization controller, the debugged electric polarization controller is connected to the EPC to be debugged, the EPC to be debugged is connected to the polarization beamsplitter at the same time, the polarization beam splitter is connected with the first light intensity measurement module and the second light intensity measurement module, and the high-voltage delay circuit is connected between the debugged electric polarization controller and the EPC to be debugged. The semiconductor laser module, the high-voltage delay circuit, the first light intensity measurement module and the second light intensity measurement module are connected to the core board, and the power supply is used for supplying power. The invention further provides an electric polarizationcontroller automatic debugging method. The device has the advantages that automatic debugging is achieved, and the defects that manual adjustment has high requirements for operators, time is wasted inoperation and efficiency is low are overcome.

Description

technical field [0001] The invention belongs to the technical field of polarization controller debugging, and in particular relates to an automatic debugging device and a debugging method for a motorized polarization controller. Background technique [0002] Polarization controller (PC): refers to a device that can transform any input polarization state into any desired output polarization state; polarization controllers are widely used in coherent optical fiber communication systems and other coherent measurement systems in the field of quantum communications. The electric polarization controller (EPC) is a fiber extrusion type polarization controller, which is an important type of polarization controller. It mainly squeezes the optical fiber through the thrust of the deformation of the piezoelectric ceramic PZT after it is energized, and produces a stress birefringence effect to change The polarization state has the advantages of simple structure and fast response time. ...
