High Temperature. High Reliability. High Performance.

Performance you can rely on, in any environment.

Overengineered for robustness, our VCSELs were originally intended to operate at temperatures as low as -55°C and as high as 150°C. At typical operating temperatures, our VCSELs really shine in terms of reliability.

Today we are developing a new generation of multiple-wavelength VCSELs for CWDM products from 850nm up to 1000nm, as well as VCSELs for sensing and lower-speed communication applications. Let us help you with your VCSEL needs.

Advanced Capabilities and Design


  • 10Gbps and 2.5Gbps VCSELs with high reliability and -55°C to +125°C operating temperature range support a wide range of operating environments
  • Transceivers, Optical Subassemblies, and VCSELs for industrial, aerospace, and commercial applications
  • Support for a variety of protocols from DC (LVDS) to ultra-broadband (100GbE)
  • In-house fabrication, device testing, and reliability testing
