2025 China Top Ten Optical Industry Technology — Application Award

Conquer Technical Challenges

Break Industrial Bottlenecks

The award-winning highly stable single-mode polarized VCSEL chips cover 760nm and 850nm wavebands, featuring high power and stable single-mode polarization performance. They have successfully overcome core technical challenges including single-mode regulation, polarization locking and high-power output, and can serve as core light sources for high-precision sensing, quantum sensing and other fields.

To meet customers' application demands, the company launches temperature-controlled TO46 module packages integrated with TEC refrigeration, fully ensuring long-term stable and reliable operation of products in various complex industrial scenarios.

High-quality Single-mode Polarized VCSEL Chips & Modules

Technical Highlights

Single-mode Stable Output

It achieves stable single transverse mode output (symmetric Gaussian beam) within the operating range. Both 850nm and 760nm products feature a side-mode suppression ratio over 25dB, delivering superior beam quality.

Stable Polarization Output

It realizes stable linearly polarized output without polarization flipping within the operating range, with the orthogonal polarization extinction ratio exceeding 20dB, ensuring excellent signal stability and high signal-to-noise ratio.

High Output Power

It achieves power breakthrough while maintaining stable single-mode polarization performance, with output power exceeding 3mW for 850nm band and over 1.5mW for 760nm band.

Excellent Beam Characteristics

The far-field divergence angle is no more than 20° with uniform energy distribution, which helps simplify the design of downstream optical systems and cut costs.

Wide Coverage of Key Wavelength Bands

850nm is applicable to ranging, velocity measurement and 3D sensing, while 760nm is dedicated to oxygen sensing, covering mainstream high-value application scenarios.

Mass Production Capability & Reliability

Built on self-developed process platforms, it supports large-scale mass production and ensures consistent performance and stable product delivery.
