Datacom VCSELs: TRUMPF achieves breakthrough in proprietary subwavelength surface grating technology

Ulm/San Diego, March 25, 2024 - TRUMPF Photonic Components, a global leader in VCSEL and photodiode solutions for data communication, announces a breakthrough with its proprietary subwavelength surface grating technology for datacom VCSELs.  “We are excited to bring patented and proven subwavelength surface-grating technology from our sensing products to datacom VCSELs where it brings a competitive edge for our 100Gbps VCSEL with lower relative intensity noise and robust polarization stability.  In addition, the GSG pad’s layout further enhances the performance due to less cross talk,” said Ralph Gudde, Vice President of Marketing and Sales at TRUMPF Photonic Components. “With the addition of these new technology tools, we are well equipped to take the lead in VCSELs with data rates of 100G and beyond.” The demonstration of the subwavelength grating on datacom VCSEL showed a stabilized polarization mode, a key benefit amongst many others.  TRUMPF also announces their future release of the100G VCSEL which, along with its many features, has a  ground-signal-ground (GSG) pad layout to further enhance the performance. This advanced technology has proven itself, being the result of a long development process and having been demonstrated on many devices and in various applications.

Advanced optical data communication systems benefit from the high-speed data transmission which the VCSEL-based technology offers. For interconnect distances below 100 meters, VCSELs are the best solution in terms of power and cost. TRUMPF is offering both VCSELs and photodiodes as a matching pair solution, in singlets, 1x4 arrays and 1x12 arrays for 14G and 25G for the NRZ applications. The same is offered for 56G PAM4 applications. The VCSELs are specifically designed to meet the demands of data centers including for AI/ML, high-performance computing, and other bandwidth-intensive applications, as they deliver stable and reliable data transmission at high speeds.
