Researchers have developed OptiLookUp, a novel photonic architecture that utilizes integrated microring resonators to create a reconfigurable optical read-only memory (ROM). This system encodes input-output mappings directly into the spectral response of photonic devices, enabling high-speed, low-latency data access. The design incorporates banked sub-arrays and optical decoding for scalability and uses transistor-based selectors for reconfigurability, achieving data rates up to 12.5 GHz. OptiLookUp is intended to implement nonlinear activation functions for photonic accelerator architectures. AI
