In China’s dynamic landscape of technological innovation, the Hangzhou Institute for Advanced Study (HIAS) of the University of Chinese Academy of Sciences shines as a rising star, fueled by youthful energy and bold ambition. Particularly in the field of single-photon avalanche diodes (SPAD) — a cutting-edge optoelectronic technology — HIAS is demonstrating extraordinary potential under the guidance of its leading research team. A key researcher from its School of Intelligent Science and Technology has served as the direct liaison with Enlitech Inc., forging a critical bridge between academia and industry. Through this deep collaboration, the development of a full-spectrum testing system and an ultra-high-resolution microscope has not only accelerated HIAS’s research but also opened new horizons for the future of SPAD technology. 

HIAS’s Beginnings: The Rise of an Emerging Force

HIAS, part of the University of Chinese Academy of Sciences, is nestled in Hangzhou, a city renowned for innovation. Established in recent years, the institute is dedicated to blending fundamental research with applied technology, driving progress in fields like optoelectronics, intelligent science, and advanced manufacturing. Though young, HIAS has swiftly gained recognition under the leadership of its flagship research group. For example, their contributions to national key research and development programs have produced breakthroughs in quantum communication and high-sensitivity detection technologies, while collaborations with top enterprises have bolstered their standing.

In the SPAD arena, HIAS is a promising newcomer. While their experience in this field is relatively fresh, this lack of historical constraints has become a strength — enabling HIAS to explore the technology with innovative perspectives, challenge conventional approaches, and pursue transformative applications. From medical imaging to quantum computing, the high sensitivity and rapid response of SPAD devices inspire HIAS’s research team. They understand that excelling in this domain demands not only creative device design but also precise measurement and analysis capabilities.

A Pivotal Role from the School of Intelligent Science and Technology

Within HIAS’s School of Intelligent Science and Technology, a core researcher has emerged as the cornerstone of this partnership. With profound expertise in SPAD device design and applications, this individual recognized that transitioning from theory to practice required a robust testing system — and Enlitech Inc. was the ideal collaborator.

Enlitech Inc., a high-tech company specializing in optoelectronic testing solutions, is celebrated for its advanced full-spectrum analysis and high-precision measurement equipment. This researcher, acting as the direct point of contact, facilitated the partnership through extensive dialogue. Beyond relaying HIAS’s requirements, they actively engaged in system design discussions, ensuring the final solution perfectly aligned with SPAD development needs.

A Spark of Collaboration: From Vision to Breakthrough

The collaboration kicked off with HIAS setting ambitious technical goals: a full-spectrum testing system paired with an ultra-high-resolution microscope capable of capturing medical imaging details in the invisible light spectrum. This presented a challenge for Enlitech Inc., but also a chance to showcase their expertise. Coordinated by the researcher, both sides engaged in rigorous technical exchanges. HIAS’s research group supplied SPAD device parameters and application scenarios, while Enlitech Inc. harnessed its capabilities to deliver a customized solution.

The outcome was breathtaking: a microscope boasting over 1000x magnification, unveiling SPAD device behavior at the microscopic level, and the SPD-Q system, which accurately measured the devices’ full-spectrum characteristics to provide dependable data. The solution not only met HIAS’s expectations but surpassed them. For instance, in medical imaging applications, the system captured cellular details under invisible light conditions, offering potential advancements in early cancer diagnosis.

Beyond supplying equipment, Enlitech Inc. evolved into a true innovation partner. They worked with HIAS to develop the PQC passive circuit, a groundbreaking component that significantly enhanced testing efficiency for SPAD and SiPH (silicon photonics) devices. The researcher’s role was pivotal, ensuring seamless integration of academic needs with industrial solutions.

Achievements and Recognition: HIAS’s Ascent

The collaboration quickly bore fruit. Leveraging Enlitech Inc.’s system, HIAS achieved multiple milestones in SPAD technology. In 2024, a paper from their research group was featured at the SPIE Annual Conference and received the “Best Emerging Technology Award.” Additionally, they secured two national invention patents related to SPAD device design and measurement techniques. These successes have propelled HIAS into the spotlight within the global academic community.

The School of Intelligent Science and Technology also gained acclaim. The researcher not only spearheaded the partnership with Enlitech Inc. but also mentored students in hands-on projects, fostering a new generation of talent. HIAS is steadily establishing itself as a vital hub for SPAD research.

Looking Ahead: Illuminating a New Chapter for SPAD

For HIAS, this partnership with Enlitech Inc. represents a leap from academic exploration to technological frontiers. The vision of its leading research group, the bridging efforts of the School of Intelligent Science and Technology, and Enlitech Inc.’s technical expertise have together crafted a triumph. Moving forward, HIAS plans to apply SPAD technology to diverse fields, such as LiDAR for autonomous driving and photon detection in high-speed communication. They are confident that their continued collaboration with Enlitech Inc. will provide a strong foundation for these ambitions.

From the theoretical groundwork laid by its research group, to the industrial advancements enabled by the School of Intelligent Science and Technology, to Enlitech Inc.’s technical empowerment, HIAS’s SPAD journey is inspiring. This collaboration transcends a mere technical achievement — it’s a testament to academia-industry synergy. As SPAD technology advances, the partnership between HIAS and Enlitech Inc. promises to deliver even more remarkable innovations.
