TRUMPF presenting next-gen VCSEL devices for LPO and CPO at ECOC
In booth C81 at the European Conference on Optical Communication (ECOC 2024) in Frankfurt, Germany (23–25 September), TRUMPF Photonic Components GmbH of Ulm, Germany (part of the TRUMPF Group) — which makes vertical-cavity surface-emitting lasers (VCSELs) and photodiodes — is presenting upcoming advances in VCSEL technology aimed at meeting evolving demands of the future datacom market.
“These improvements focus on increasing functionality per chip area to support low-noise LPO [linear-drive pluggable optics] links and densely integrated CPO [co-packaged optics] technology,” says Roman Koerner, head of R&D. Key innovations include subwavelength gratings to reduce relative intensity noise (RIN) and burst noise, as well as composite VCSELs for improved single-mode robustness, faster speed and lower thermal impedance. Designed for wavelengths like 1060nm and 1310nm to minimize fiber attenuation, this technology will play a crucial role in the next generation of high-performance optical transceivers, reckons the firm.
Advanced optical data communication systems benefit from the high-speed data transmission that the VCSEL-based technology offers. TRUMPF says that it continues to invest heavily in its technology for higher data rates and is offering both VCSELs and photodiodes as a matching pair solution in various layouts 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.
