TRUMPF applies proprietary subwavelength surface-grating technology to datacom VCSELs
TRUMPF Photonic Components GmbH of Ulm, Germany (part of the TRUMPF Group) — which makes vertical-cavity surface-emitting lasers (VCSELs) and photodiodes for the consumer electronics, datacoms, industrial sensing & heat treatment and automotive markets — has announced a “breakthrough” by transferring its proprietary, patented subwavelength surface-grating technology (developed since 2006 and implemented on tens of millions of VCSELs for sensing applications) from its sensing products to datacom VCSELs, where it is said to bring a competitive edge for the firm’s 100Gbps VCSEL with lower relative intensity noise (RIN) and robust polarization stability.
“In addition, the ground–signal–ground (GSG) pad’s layout further enhances the performance due to less cross-talk,” says Ralph Gudde, VP of marketing & 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,” he reckons. The demonstration of the subwavelength grating on the datacom VCSEL showed a stabilized polarization mode, a key benefit among many others.
TRUMPF has also announced the future release of the 100G VCSEL which has a ground–signal–ground (GSG) pad layout to further enhance the performance. The firm says that the technology has proven itself, being the result of a long development process and having been demonstrated on many devices and in various applications.
TRUMPF Photonic Components is exhibiting in booth 2000 at the Optical Fiber Communication Conference & Exposition (OFC 2024) in San Diego, CA, USA (26–28 March).
