In this project, we propose for the first time an optical Streaming Processing Unit (SPU) that leverages brain-inspired advanced multidimensional computing operators including differentiation, integration, projection operations, low-resolution inference which are realized by photonic integrated circuits and integrates them with photonic neural networks. This optical SPU completes AI processing instantaneously through optical propagation, enabling energy-efficient optical streaming computations. It provides a new analog processor that balances versatility and scalability for constructing large-scale AI models through chiplet-based interconnect networking.

Outline

We are developing a photonic tensor core capable of executing large-scale matrix multiplication, a critical operation in AI computation, with high speed and energy efficiency. To ensure accurate matrix calculations, preventing signal interference between elements is essential. By utilizing microcomb technology and heterogeneous material integration, we aim to achieve multiplexing across “wavelength × time × space,” enabling large-scale matrix computations.

Outline

For the realization of next-generation information processing at terahertz rates, optoelectronic interfaces for spin manipulation and spin state read-out that use terahertz wave should be useful. In this project, we attempt to develop a technology based on a magnetic spectroscopy technique that uses the most strong terahertz wave sources in the world and a metallic metamaterial resonator structure to generate and control magnon and spin current in magnets. By combining the efforts of experimentalists and theorists, we consider that it is possible to develop a new fundamental technology for terahertz spintronics.
