Abstract

The super luminescent diode light source (SLD) is an important component in fiber-optic gyroscope. And wavelength temperature stability is one of its key parameters. Effective temperature compensation system has been designed in previous works to stabilize its wavelength stability, which consists of driver module and thermal control module. For the driver module, temperature compensation model should be used to obtain stabilized current output. And for thermal control module, optical power change model is needed to obtain stabilized mean wavelength. Both models need to be well-established. In this work, intelligent modelling systems have been designed and realized for driver module and thermal control module. And fuzzy control algorithm is used for fine adjustment during modelling process. The intelligent modelling systems consequently improved the modelling efficiency and accuracy, and further improved the mean wavelength stability of SLD light source. Compared with traditional methods of mean wavelength drift suppression, after using the final model established by intelligent modelling systems, a wavelength stability improvement of one order of magnitude has been finally demonstrated.
