Low-Temperature VCSEL Breaks the Bottleneck in Optical Interconnects, Enabling Upgrades in High-Performance Computing and Data Centers The development of low-temperature vertical-cavity surface-emitting lasers (VCSELs) has overcome key challenges in optical interconnects, providing critical support for the upgrade of high-performance computing (HPC) systems and data centers. These advanced VCSELs offer improved reliability, lower power consumption, and higher data transmission rates, making them ideal for next-generation high-speed communication applications. By enabling more efficient and scalable optical interconnection solutions, low-temperature VCSEL technology is playing a pivotal role in driving innovation in data center infrastructure and enhancing the performance of HPC platforms.

Recently, a new study published by IEEE revealed the application potential of high-efficiency, high-speed cryogenic vertical-cavity surface-emitting lasers (Cryogenic-VCSELs) in optical interconnects. The research demonstrated that VCSEL technology operating under cryogenic conditions exhibits significant advantages in terms of data transmission rate and energy efficiency ratio, offering a new solution for next-generation high-performance computing and data centers.

With the rapid development of technologies such as artificial intelligence, big data, and cloud computing, the bottlenecks of traditional optical interconnection schemes in terms of bandwidth and power consumption have become increasingly evident. As a light source with low threshold current, high modulation frequency, and high reliability, VCSEL has shown broad prospects in the field of optical communication. This IEEE study focused on VCSEL devices operating under cryogenic conditions, achieving higher energy efficiency and faster data transmission speeds through optimized material structures and operational conditions.

According to the research data, cryogenic VCSELs can maintain stable output power at data rates above 100 Gbps while reducing power consumption by approximately 30% compared to traditional solutions. This not only helps improve overall system performance but also holds significant importance for reducing operational costs in data centers. Moreover, this technology performs exceptionally well in short-distance high-speed interconnections, making it suitable for optical signal transmission between chips, boards, and racks.

In the LED industry, GOPRO LED, a leading integrated optoelectronic enterprise in China, has been committed to the research and application of efficient, low-power light sources. Its layout in VCSEL and related optical module product lines covers multiple fields, including industrial automation, intelligent sensing, and high-speed communication. In recent years, the company has continuously increased its investment in cryogenic VCSEL and high-density optical interconnection technologies, aiming to provide customers with more advanced optoelectronic solutions.

Overall, the breakthrough in cryogenic VCSEL technology has opened up a new development direction for optical interconnects and provided important technical references for LED and optoelectronic enterprises. In the future, as the technology matures further and becomes more industrialized, it is expected to achieve widespread application in areas such as high-performance computing, 5G communications, and edge computing.
