Imaging and Sensing
Robust, compact quantum sensors to deliver unprecedented precision: Accuracy and sensitivity for applications including medical, navigation, brain computer interfaces (BCI), and many more
Katrin Kobe (Bosch Quantum Sensing)
Quantum sensing may be less well known than quantum computing but its impact on our world may be just as significant. Quantum sensors promise accuracy 1,000 times greater than that provided by today's conventional sensors, opening up new applications in medicine, navigation and more. Quantum sensing is also closer to market readiness than quantum computing.

The quantum revolution in vehicle sensor technology: How quantum dots are empowering vehicle safety and automation features
Hao Pang (Quantum Science)
With technology like lidar heralding a revolution in vehicle automation, SWIR (short-wave infrared) imaging and sensing will become increasingly vital to the automotive sector. Quantum dots, nanoscale semiconductors tunable to SWIR wavelengths, could provide the answer to empowering SWIR and bringing enhanced capability to the mass market.

Technology Feature
Optical neurons to interconnect sensors and artificial brains in autonomous vehicles: Fiber optics connectivity based on long-wavelength VCSELs and fully-integrated and adaptive electronics
Rubén Pérez-Aranda (KDPOF) & Joseph Pankert (Trumpf Photonic Components)
With the ever-increasing need for faster data communication in cars, electrical interconnects are beginning to show bandwidth and electromagnetic compatibility limitations. The new IEEE 802.3cz ethernet physical layer has been developed specifically to meet these needs, based on a long-wavelength multimode VCSEL (vertical cavity surface-emitting laser) and mature bend-insensitive multimode fibers. A major innovation is taking place that will make automotive-grade, multigigabit optical transceivers possible.

Laser Micromachining
High-speed laser drilling to scale up fuel cells and hydrogen electrolyzers: Fabricating microholes with precise geometry, superior quality, and high production rates
Mitchell Leering (MTC), Cliff Jolliffe (Physik Instrumente), and Sundar Marimuthu (MTC)
Scaling up clean hydrogen production using renewable energy is essential for decarbonizing a range of sectors, including transportation, chemicals, and steel, where reducing emissions and achieving net-zero targets have proven to be challenging. Advances in laser-based manufacturing, particularly ultra-high-speed laser drilling, are crucial for economically producing and scaling up hydrogen components, including high-temperature hydrogen electrolyzers (HTHE).

Laser Sources
Epitaxial regrowth: How GaAs is the key to unlocking new semiconductor laser markets
Richard Hogg (III-V Epi)
How can design engineers use epitaxial regrowth to enhance semiconductor laser performance and unlock new markets? First, we need to take a closer look at the relatively mature, epitaxial regrowth process for indium phosphide (InP) lasers, commonly used in 5G, datacomms, telecoms and co-located optics applications. Then we can consider gallium arsenide (GaAs), a less mature material system, which suits a multitude of emerging industrial, biomedical imaging, datacomms, and sensing laser applications.

Optical Measurement Technology
Photonic blood glucose measurement with infrared quantum cascade lasers: A novel non-invasive and pain-free glucometer for diabetes patients
Sergius Janik, Thorsten Lubinski, Michael Kaluza, and Werner Mäntele (all: Diamontech)
Diabetes patients rely on frequent measurement of blood glucose that is presently performed by painful pricking and analysis of a drop of blood. Diamontech has developed a noninvasive technique that targets a prominent mid-infrared signature of glucose. This technique uses quantum cascade lasers and photothermal detection. Clinical validation has proven an accuracy similar to current invasive techniques.
