Controller device bias for IQ electro optical modulators, based on the current

摘要

Summary of the bias controller device for electro optical modulators IQ, based on current. The new controller device bias for electro optical modulators IQ, based on current and its method of operation, which is related to the modulation signals for optical communication systems and equipment used for this purpose.Particularly is directed to the development of systems for closed loop control of the operation point of the electro optical modulators controlled by current. This invention has as main objective to provide a device and a method for controlling the phase of the optical signal generated for each of the components I and Q, which ensures the operation point suitable for optical modulators.Based on the introduction and monitoring of electric current? And, therefore, the temperature (via the thermoelectric effect)? For the adjustment of bias. The use of electronic circuits capable of implementing algorithms developed specifically for processing and signal processing of optical feedback.The control system uses the intensity of optical power output of the modulators as feedback signal. By means of monitoring the intensity of these signals, performs a series of processes and treatments of the data and, as a result, infers a precise tuning of the operation point of the modulator.Also includes a boot method which enables the simplification of the flow of control. ????? ????? ????? ????? 1 / 1
