VCSELs rev up for life in the fast lane
Multi-junction vertical-cavity surface-emitting lasers are likely to displace LEDs and edge-emitting lasers in sensing, finds Andy Extance

Electro Optics share's the main events and themes on its radar at this year's show in San Francisco
The device could dramatically increase the quality of life for diabetics, who currently have to prick their finger or wear an implant to monitor glucose levels
The next generation of single-mode VCSEL products offers lower power consumption, while maintaining high output performance
Launched at Photonics West, the VCSEL with stable linear polarisation and meta-optics uses only two components to create both flood and structured light illumination
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
As microscopes become ever more powerful, a growing band of businesses are racing to make the latest technologies more accessible and more affordable, reports Rebecca Pool
Illustration of a three-dimensional crystal with various types of confining centres. (a) Crystal with four confining centres, each trapping waves (yellow) in all three dimensions simultaneously. (b) Crystal with a linear confining centre where waves can propagate in one dimension, analogous to an optical fibre. (c) Crystal with a planar confining centre where waves can propagate in two dimensions, analogous to a 2D electron gas. (Image: Vos et al.)
Newly discovered fundamental rules have been embedded into software to dramatically optimise the design of photonic integrated circuits
