DEVICE FOR STABILIZING SPECTRUM OF MICRO-RING RESONATOR

摘要

A device for stabilizing a spectrum of a micro-ring resonator (1), comprising a micro-ring resonator (1), a signal processing unit (2), an FPGA control unit (3), a source meter functional module (4) and a heater drive unit (5), wherein after a current is input into a PIN junction of the micro-ring resonator (1), the amount of variation of a voltage at two ends of the PIN junction of the micro-ring resonator (1) caused by temperature variation is detected, and then after the amount of variation of the voltage is processed through the signal processing unit (2) and the FPGA control unit (3), a voltage drive signal for stabilizing a spectrum of the micro-ring resonator (1) is generated. In the actual configuration, the PIN junction detects the working temperature of each micro-ring switch in real time, so that the problem that a large number of micro-rings cannot be positioned is solved, moreover, no additional functional devices are needed, while the device has the advantages of having high temperature detection speed, being low in cost and being simple in design process and easy to operate, and the device can meet the requirements of high speed development of current optical communication systems.
