Title:
METHOD AND DEVICE FOR CONTROLLING DIGITAL AUTOMATIC BIAS VOLTAGE OF ELECTRO-OPTICAL OPTICAL REGULATOR
Document Type and Number:
WIPO Patent Application WO/2016/127800
Kind Code:
A1
Abstract:
A method and device for controlling digital automatic bias voltage of an electro-optical type optical regulator, capable of continuously correcting operating bias voltage in an optical regulator operating process, such that operating performance of the optical regulator is more stable; the control method comprises the following steps: inputting scanning bias voltage to the optical regulator (s101); calculating half-wave voltage of the optical regulator (s105); calculating an error feedback coefficient and dither amplitude of a dither signal according to the half-wave voltage (s106); inputting the operating bias voltage and the dither signal to the optical regulator (s107); calculating a harmonic amplitude and a phase difference (s111); calculating, by combining the error feedback coefficient, the harmonic amplitude and the operating bias voltage, to obtain a new bias voltage according to the phase difference (s112); taking the new bias voltage as the operating bias voltage (s113), and returning to the step of inputting the operating bias voltage to the optical regulator.
