On Stability Control Technology of Bias Point of High-speed Electro-optic Modulators
Based on the characteristics of electro-optic and feedback modulations of high-speed electro-optic modulators,this paper proposes a bias point stability control technology based on pilot method to ad-dress the issue of unstable modulation performance.The technology can maintain stable modulation of high-speed electro-optic modulators for more than 32 hours,greatly ensuring the fidelity of microwave ra-dio frequency signal modulation.Meanwhile,the controller has obvious advantages such as simple struc-ture,low cost and high stability,ensuring stable loading of radio frequency signals for high-speed electro-optic modulators under complex operating conditions.
