Abstract
A practical frequency stabilization method for opto-electronic oscillators (OEOs) using an Adaptive Proportional-Integral-Derivative (PID) controller with Trend-based Adjustment (APTA) is proposed and experimentally demonstrated. The method dynamically adjusts the laser driver current of the distributed feedback (DFB), enhancing frequency stability without needing costly tunable lasers. The APTA approach achieves a frequency drift reduction to ±0.005 ppm/K and an Allan deviation of
$8.5 \times \; 10^{-11}$
at 1000 s under thermal variations while maintaining phase noise performance.
期刊介绍:
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
