TRUMPF improves performance of datacom VCSELs with proprietary subwavelength surface grating technology

Ulm/Frankfurt, September 23, 2024 - TRUMPF Photonic Components, a global leader in VCSEL and photodiode solutions for data communication, has improved its proprietary subwavelength surface grating technology for datacom VCSELs. Subwavelength grating technology leads to better relative intensity noise (RIN) performance, reduces sensitivity against optical feedback and avoids polarization flips. As a result, the signal quality in a complex optical link is improved and enables higher data rates without changing the light current voltage (LIV) characteristics. This breakthrough technology with its benefits works for all offered wavelengths.

“Our proprietary, advanced subwavelength grating technology has been a proven, key feature in our VCSEL solutions for two decades now and has been employed in many millions of consumer devices.” said Ralph Gudde, TRUMPF’s Vice President of Marketing and Sales. “We are pleased to see that this technology found its way into our datacom products and offers customers a performance that sets them apart,” he added.

Advanced optical data communication systems benefit from the high-speed data transmission which the VCSEL-based technology offers. TRUMPF’s new 100G wavelength division multiplexing VCSELs emitting at 850nm, 880nm, 910nm and 940nm have a ground-signal-ground (GSG) pad layout and are flip-chip bondable. It will have a bandwidth of 25 GHz, is fully passivated and mechanically protected. TRUMPF is offering both VCSELs and photodiodes as a matching pair solution in various configurations like singlets, 1x2, 1x4, 1x8 and/or 1x12 arrays. The VCSELs are specifically designed to meet the demands of data centers, AI/ML, high-performance computing, and other bandwidth-intensive applications, as they deliver stable and reliable data transmission at high speeds.
