The 2025 IFOC Stone Information Optical Communication Annual Forum & Awards Ceremony has ended. Over 500 industry guests attended the event focusing on market, technology, opportunities and talents. Optet Technology’s back-illuminated 200Gbps PIN PD won the Innovation Technology Award, showcasing its leading R&D in high-end optical chips.

In-Depth Teardown of the Award-Winning Product: Four Performance Breakpoints Define a New Industry Benchmark

As a core device supporting cutting-edge fields such as AI intelligent computing and high-speed interconnection, Optet Technology’s back-illuminated 200Gbps PIN photodetector (PD) has achieved comprehensive breakthroughs in key performance indicators, perfectly meeting the requirements of 800G/1.6T optical communication systems:

Ultra-wide bandwidth leading the industry: With a bandwidth of up to 52 GHz at -2 V bias, it precisely matches the PAM4 modulation format and provides sufficient performance redundancy for next-generation high-speed optical modules.

High sensitivity for exceptional light capture: It achieves a responsivity of 0.7 A/W at the 1310 nm communication band, effectively improving receiver sensitivity and enabling low-power operation of optical modules.

Ultra-low noise ensures transmission quality: By optimizing semiconductor materials and structural design, the dark current is as low as 0.35 nA, and device capacitance is only 27 fF, significantly reducing system bit error rate and ensuring complete transmission of high-frequency signals.

Flexible adaptation to multiple scenarios: Available in single-channel and four-channel array configurations, it supports bare die, COB, and TO-specific packaging, and is widely used in core scenarios such as AI cluster interconnection and short-reach transmission in data centers.

“The breakthrough of this product solves the industry pain point of ‘balancing bandwidth and noise’ in high-speed optical reception,” said the technical director of Optet Technology. Currently, the chip has been validated by first-tier optical module customers, with feedback exceeding expectations.

In-Depth Decoding of R&D Capabilities: Talents and Patents Build a Technical Moat

Behind the product’s outstanding performance lies nearly a decade of technical accumulation by Optet Technology in the field of optical chips. As a high-tech enterprise founded by a team of national and provincial leading talents, the company has built a high-level R&D team led by several doctors and professor-level experts, forming a full-chain technical capability from R&D design to chip manufacturing.

By the end of 2025, Optet Technology has accumulated nearly 100 invention patents, many of which directly empower the award-winning product: the on-trough lens fabrication technology improves chip sensitivity by optimizing optical signal focusing, and the embedded metal contact isolation deep trench technology achieves dual improvements in device performance and mass production efficiency... It is the continuous force of technological innovation that supports the product in winning industry awards and gaining widespread recognition from the industry.

Riding the AI Wave to Unlock the Future of Optical Interconnection

Currently, the wave of AI intelligent computing is driving explosive growth in the optical communication market. LightCounting predicts that the AI-related optical device market will grow at an annual rate of 30–35% between 2025 and 2026. Optet Technology’s award-winning product will provide core support for the domestic replacement of 800G/1.6T optical modules.

This win of the Stone Information Innovation Technology Award is not only a high recognition of Optet Technology’s R&D capabilities but also an important milestone for China’s high-end optical chips. In the future, adhering to the philosophy of “Progress, Pragmatism, Rigor, Professionalism,” Optet Technology will continue to deepen its technical research and contribute more “China Chips” power to the optical communication industry.
