Multi-junction vertical-cavity surface-emitting lasers are likely to displace LEDs and edge-emitting lasers in sensing, finds Andy Extance
More than 1,200 exhibitors will be on the show floor this year, with more than 4,500 technical presentation taking place in tandem. (Image: SPIE)
Electro Optics share's the main events and themes on its radar at this year's show in San Francisco
Similar to a smartwatch, the developed glucose monitor will be wearable on the wrist for the convenience of hundreds of millions of diabetics worldwide. (Image: Shutterstock/Chaay_Tee)
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 collaboration has yielded a 200m, long-range VCSEL-based hybrid solid-state lidar solution for ADAS. (Image: Hesai)
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
