vertical-cavity surface-emitting lasers News
Photonic Transceivers Drive Ethernet Solutions
Sep 24, 2020 — Market experts in the European Union agree on the need for internet service providers and hyperscale data centers to reach bandwidths of 800 Gbit/s to 1.6 Tbit/s for their users by 2025. To meet this target, industrial suppliers must adopt new...
Backstory: VCSEL Breakthrough, 1989
Jun 2, 2019 — Thursday, May 11, 1989 It was the first test of our first attempt to fabricate VCSELs. They lit up! Thousands of VCSELs on a crumb-size chip lased readily with low threshold currents (1s of mA), the smallest lasers in the world. The original ~6-...

Forecast: VCSEL Market to Grow to $2.1B by 2018
WELLESLEY, Mass., Aug. 13, 2014 — Vertical-cavity surface-emitting lasers (VCSELs) will be a $2.1 billion market, growing 33.1 percent from 2013 to 2018, BCC Research predicts. Optical fiber data transmission is expected to record the highest growth within the VCSEL market: $615.1...
The Coming Market for Optical Fiber and Cable
Feb 1, 2012 — “The market for optical fiber cable has shifted dramatically in the past five years to local deployments, away from long haul and regional.” The market for optical fiber and cable is a critical piece of the broader optical components...
Marching Toward 1-s Movie Downloads
Apr 1, 2007 — Researchers at IBM’s T.J. Watson Research Center in Yorktown Heights, N.Y., have developed a novel optical transceiver that can move data at a rate of 160 Gb/s — fast enough to enable consumers to download a high-definition movie in about one...
Companies Form Distribution Pact
Sep 1, 2005 — Laser Components IG Inc. of Hudson, N.H., and Ulm Photonics GmbH in Germany have entered into an exclusive agreement to distribute Ulm's vertical-cavity surface-emitting lasers in North America. The companies will work together to provide technical...
High-Power, High-Efficiency VCSELs Pursue the Goal
Feb 1, 2005 — At Princeton Optronics Inc., we intend to meet the goals of the SHEDS program using vertical-cavity surface-emitting lasers (VCSELs). These devices differ from edge-emitting lasers in that their output beam is perpendicular to the top surface of the...
VCSEL for Telecom Features Curved Mirror for Single-Mode Operation
Jun 1, 2004 — Vertical-cavity surface-emitting lasers (VCSELs) based on microelectromechanical systems (MEMS) are attractive candidates for telecom lasers because they can be tested while still in wafer form, their inherently short resonators ensure...
Laser Analyzer Delivers 'Hands-On' Automation
Mar 1, 2004 — Although the general slump of the telecommunications sector continues, many companies in the fiber optics industry require solutions for automating their processes as insurance for their survival. Current production volumes do not justify the...
Modal Characteristics of Holey VCSELs Studied
Mar 1, 2004 — Researchers from the University of Illinois at Urbana-Champaign and Furukawa Electric Co. in Yokohama, Japan, have presented the results of their investigation into the modal characteristics of vertical-cavity surface-emitting lasers (VCSELs) with...
VCSELs Go Long-Wave
Sep 1, 2003 — Vertical-cavity surface-emitting lasers (VCSELs) are now routinely used in photonics applications such as telecommunications, primarily at 850 nm. Their long-wavelength cousins — 1300- and 1550-nm devices — still have some way to go before they...
