CMOS compatible photonic processors operate at the intersection of electronic and optical domains, where signal propagation requires precision engineering at sub-micron scales. Current implementations face coupling losses of 1-3 dB at electronic-photonic interfaces, thermal sensitivity of approximately 0.1 nm/°C for resonant structures, and crosstalk challenges when integrating components with varying operational wavelengths typically between 1310-1550 nm.

The fundamental challenge lies in developing scalable architectures that leverage the parallelism and energy efficiency of photonics while maintaining compatibility with established semiconductor manufacturing processes.

This page brings together solutions from recent research—including segmented waveguide structures with integrated photodetector pads, field-programmable photonic gate arrays with non-uniform mesh arrangements, liquid crystal-based reconfigurable optical networks, and three-dimensional architectures leveraging VCSEL arrays for neural network implementation. These and other approaches address the practical demands of high-bandwidth interconnects, matrix multiplication accelerators, and other computational structures needed for next-generation information processing systems.
