“…Automotive networking represents another harsh environment application, with an operating temperature from -40 to +125°C. VCSELs for this application are under development [21], [22] and VCSEL-based networking standards are developed in the IEEE P802.3cz Multi-Gigabit Optical Automotive Ethernet Task Force for lane rates up to 50 Gbps [23]. Optical networking in radars and other military/defense systems is yet another harsh environment application for which rugged, high-capacity VCSEL-based transceivers are developed [24].…”

Vertical cavity surface-emitting laser (VCSEL)-based optical interconnects (OI) are crucial for high-speed data transmission in data centers, supercomputers, and vehicles, yet their performance is challenged by harsh and fluctuating thermal conditions. This paper addresses these challenges by integrating an ordinary differential equation (ODE) solver within the VCSEL communication chain, leveraging the adjoint method to enable effective gradient-based optimization of pre-equalizer weights. We propose a machine learning (ML) approach to optimize feed-forward equalizer (FFE) weights for VCSEL transceivers, which significantly enhances signal integrity by managing inter-symbol interference (ISI) and reducing the symbol error rate (SER).
