Role overview

Job description

The rapid expansion of artificial intelligence (AI) applications across cloud and edge environments is driving the need for highly efficient hardware capable of supporting increasingly demanding workloads. Among these, matrix multiplication – particularly General Matrix Multiplication (GEMM) – remains the dominant computational kernel in modern AI models, including deep neural networks and transformer architectures. Conventional electronic accelerators, while highly optimized, face growing challenges related to energy consumption, data movement, and scalability. Silicon photonics has emerged as a promising technology to address these limitations by enabling highbandwidth, low-latency, and potentially energy-efficient computation through optical signal processing. In particular, recent advances in photonic computing leveraging phase-change materials (PCM) offer new opportunities for imple
