TRUMPF demos linear performance of 850nm 100G VCSEL and PD in Optomind’s transceiver
In booth C4107 at the European Conference on Optical Communication (ECOC 2025) in Copenhagen, Denmark (29 September–1 October), TRUMPF Photonic Components GmbH of Ulm, Germany (part of the TRUMPF Group) — which makes vertical-cavity surface-emitting lasers (VCSELs) and photodiodes for datacoms — is showcasing linear performance of its new PAM4 100Gbps, 850nm multimode VCSEL in collaboration with customer Optomind Inc of Suwon, South Korea, which provides optical interconnect solutions for data centers including artificial intelligence (AI) and high-performance computing (HPC) networks. Along with the VCSEL, TRUMPF also offers a 100G wideband (842–948nm) photodiode that can be used to further optimize the link.
“TRUMPF’s 100G VCSEL’s excellent linearity over a wide temperature range, paired with TRUMPF’s 100G photodiode, enable solid performance and extra design margins, yielding a superior transceiver design,” comments Optomind’s chief marketing officer Yung Son. “We look forward to further strengthening our already cutting-edge products with new technologies in collaboration with TRUMPF,” he adds.
“Our continuing partnership with Optomind, which allows us to validate the benefits of our new technologies in a real-world application, is immensely valuable to us,” comments TRUMPF’s VP of marketing & sales Ralph Gudde. “We will continue to work together in the future towards developing new products based on our devices featuring innovative technologies such as higher data rate, longer wavelengths and subwavelength grating.”
Advanced optical data communication systems benefit from the high-speed data transmission that the VCSEL-based technology offers, says TRUMPF. For interconnect distances of up to 100m, VCSELs are the best solution in terms of power, cost and the productivity of SR modules. TRUMPF is offering both VCSELs and photodiodes as a matching-pair solution, in singlets, 1x4 arrays and 1x12 arrays for 14G and 25G for NRZ applications. The same is offered for 56G PAM4 applications and now for the 100G PAM4 VCSEL. The VCSELs are specifically designed and implemented to meet the requirements of hyperscale data centers including demands for AI/ML applications, high-performance computing systems (HPC), and other bandwidth-intensive applications, as they deliver high performance and reliable data transmission at high speeds.
