Excited to share my latest work on chirp compensation using a nonlinear model (NLM) to mitigate the effects of directly modulated VCSELs (DMVCSELs)!
By leveraging a Hammerstein-Wiener (HW) system, our trained model utilizes a phase modulator (PM) to correct phase distortions in optical signals. The system takes an electrical modulated data signal from the DAC, processes it through the NLM, and applies a time-dependent phase correction to align with the RF signal. This significantly reduces chirp-induced impairments, enhancing signal integrity and transmission quality.
🔬 Key Highlights:
✅ Nonlinear modeling for precise chirp compensation
✅ HW system applies nonlinear functions to capture real-world signal dynamics
✅ Improved optical transmission performance using phase correction
The implementation structure (Fig. 5-19) showcases how the HW system efficiently models nonlinearities while maintaining system dynamics. Looking forward to further developments in this area!
