Optical Computing Startup Photonics Core Technology Raises Seed Funding

Photonics Core Technology (Beijing) Co., Ltd., a Beijing-based innovator in optoelectronic fusion computing chips, has successfully closed a multi-million RMB angel round financing. The investment was co-led by Suzhou Xinyang Fund, Chixing Ventures, and Shengjing Capital, with participation from Kaiyuan Ventures. This funding marks a significant step for the startup, which emerged in 2024 with a mission to address the escalating power and memory constraints faced by traditional electronic processors.

Founded by Dr. Yang Qisheng, an alumnus of Tsinghua University's Integrated Circuit College, Photonics Core Technology is leveraging a unique 'full-wave' optical computing architecture. This approach diverges from conventional methods by treating the entire optical chip as a programmable physical operator, utilizing sophisticated meta-surface technology to precisely control light wavefronts. This allows for the integration of various optical phenomena like diffraction, interference, and scattering into a unified design framework, aiming to unlock the full performance potential of optical computation.

The company's core innovation lies in its 'full-wave meta-surface' technology. Unlike traditional designs that rely on assembling discrete optical components, this method enables a significantly higher computational density. Photonics Core Technology claims its meta-surface chips can achieve a processing power density of up to 1000 TOPS per square millimeter, a substantial leap over existing solutions. This high integration capability is crucial for heterogeneous integration with electronic chips via the Chiplet approach, promising peak integration and energy efficiency for optical analog computing.

Beyond hardware, Photonics Core Technology is developing a comprehensive software toolchain to facilitate the adoption of its optical computing solutions. This includes an independently developed optoelectronic co-simulation design tool, EPDA, which streamlines the simulation and optimization process from device to system level. The software aims to harness the high-parallelism and low-power advantages of optical chips for linear computations, while complementing them with the established strengths of electronic chips in non-linear operations and data management. The company is also building compilers, drivers, and operator libraries to lower the barrier for developers.

The optical computing sector is gaining considerable traction as a potential successor to Moore's Law, with numerous research institutions and startups exploring various architectural approaches. Photonics Core Technology's focus on a 'full-wave' strategy, enabled by meta-surfaces, positions it to tackle complex computational tasks with unprecedented efficiency. The company has completed initial principle verification and is progressing towards engineering validation, with plans to develop customized chips based on client requirements and finalize testing, packaging, and software-hardware co-debugging.

This strategic investment underscores the growing investor confidence in advanced computing paradigms. The demand for more powerful and energy-efficient AI processing is driving innovation in areas like optical computing, which promises to overcome the limitations of silicon-based electronics. The successful funding round for Photonics Core Technology signals a promising future for the company and highlights the potential of novel architectures to redefine computational capabilities in the coming years.
