The partners will incorporate VCSEL array light sources into lidar to improve its cost and scalability
The £50k project is focused on next-generation quantum timing applications in strontium-atom-based, optical clocks
Power consumption is critical in many sensing applications that use VCSELs. This whitepaper discusses how the characterization of VCSELs in both continuous wave (CW) and pulsed operation mode can be simplified.
Trumpf has delivered its billionth vertical cavity surface emitting laser (VCSEL) to European partner STMicroelectronics
Trumpf is acquiring 100 per cent of Photonics GmbH from Philips, headquartered in Ulm, Germany. The move, which represents Trumpf's largest acquisition since buying JFY in China in 2013, opens up a new market segment for Trumpf to complement its existing high-power diode laser business
The cumulative milestone comes after two years of significant growth in demand for vertical cavity surface emitting lasers, driven by trends such as 3D face recognition in smartphones
Thorlabs has released new versions of its 1,300nm MEMS‐VCSEL swept‐wavelength laser sources
Professor Paul Shore led the team that micromachined the complex mirrors within James Webb’s mid-infrared instrument. He chats about the technical lessons learnt
EMF invested a great deal of time and effort in developing a coating system for producing long-lasting diamond like carbon (DLC) coatings on chalcogenides at scale
The properties of chalcogenide glass optics have opened up a number of use cases in infrared optics applications and beyond. This article assesses how some of the associated manufacturing and handling challenges of this material can be overcome
