PHOTONICS WEST 2024 ROUND-UP
“Products costs are reduced, while maintaining the same high-resolution image quality”
in high-contrast environments such as sunlight and snow. The DPT optical module has a wider illumination window compared with traditional LEDs. In the same area, the number of microLEDs used can be reduced, meaning product costs are reduced while maintaining the same high-resolution image quality.
Autonomy winner: Anello Photonics’ silicon photonics optical gyroscope
The silicon photonics optical gyroscope (SiPhOG) is a low-noise and low-drift optical gyroscope smart sensor that replaces the discrete optical components (couplers, modulators, and detector) found in a traditional fibre optic gyroscope using photonic integrated circuit technology. The result is what the company says is the smallest optical gyroscope in the world, which enables reliable and accurate navigation and positioning across many autonomous applications. The SiPhOG provides a massive reduction in component costs and significant reduction in dimensional volume, as compared to an equivalent high-performance traditional fibre optic gyroscope implementation.
Biomedical winner: JenLab’s multiphoton tomograph with femtosecond fibre laser JenLab’s moveable multiphoton tomograph, called MPTcompact, is based on an ultracompact chiller-free femtosecond fibre laser located in the 360° measurement head for two-photon autofluorescence, second- harmonic generation imaging, fluorescence lifetime imaging microscopy, and reflectance confocal microscopy. With its 360° measurement capability, the tomograph can be used for tissue imaging, such as the tracking of fluorescent proteins in transgenic animals, as well as for material analysis.

It operates at a near infrared wavelength of 780nm.
Cameras and imaging winner: Prelude functional imaging microscope from Thorlabs Thorlabs’ integrated two-photon microscopy system is suitable for samples with demanding positioning requirements. The Prelude microscope offers motorised XYZ translation and manually operated rotation through a ±90° range, providing multi-axis access to samples at non-vertical angles. The system contains a near-infrared 920nm femtosecond pulsed laser and integrated filter set. The fibre- coupled laser source allows for easy assembly, disassembly, and relocation of the system compared to multiphoton microscopes that use free- space laser beams and mirrors. Two microelectromechanical system (MEMS) scanners provide 4.7kHz resonant-MEMS scanning with low noise.
Lasers winner: Ekspla’s industrial femtosecond laser Designed for micromachining, the FemtoLux 30 from Ekspla offers non-stop 24/7/365 zero- maintenance operation with its dry cooling technology. The laser has a tunable pulse
duration from <350 fs to 1ps and can operate in a broad AOM controlled range of pulse repetition rates from a single shot to 4MHz. The maximum pulse energy is more than 100µJ operating with single pulses and can reach more than 450µJ in burst mode, ensuring higher ablation rates and processing throughput for different materials. The FemtoLux 30 beam parameters will meet the requirements of the most demanding materials and micro-machining applications, the company says.
Quantum tech winner: Qunnect’s auto polarisation compensator Regardless of qubit type, large- scale quantum networking is not possible without optimally compensating for the optical fibres’ polarisation drift. Qunnect’s automated polarisation compensating devices are low-loss, fast modules to compensate for any
The Hamamatsu Vision Suite
Showcasing the inspiring future of photonics The Hamamatsu Photonics Vision Suite made its debut at Photonics West this year, proving to be a major hit with attendees. Through a blend of interactive demos and presentations across six categories, the suite showcased a curated selection of photonics technologies, applications, and research designed to inspire visitors with the future potential and possibilities of photonics: •Wellbeing: demonstrated light-based sensing and imaging systems enabling disease diagnosis and continuous health monitoring, dramatically improving the speed and quality of healthcare •Mind: shared how neural imaging and optogenetics are being used to observe and manipulate neural activities with exceptional precision, non-invasively •Everyday Living: highlighting photonics’ ubiquitous existence in society, from the lidar sensors guiding vehicles to the laser systems assembling our smartphones and the optical networks transferring our data •Quantum Technology: showcased the essential role photonics plays in the rapidly evolving world of quantum-based sensing, imaging, cryptography, positioning navigation and timing •Earth: promoted photonics’ ability to secure a sustainable and cleaner environment, for example using optical sensors and spectroscopy techniques to detect atmospheric pollutants •Space: informed attendees on the cutting-edge optical and spectroscopy systems enabling scientists to determine the composition and properties of the countless exoplanets, distant stars, and galaxies populating the cosmos. Hidden away from the hustle and bustle of this year’s
exceptionally busy exhibition floor, the Hamamatsu Vision Suite was the perfect place for attendees to retreat to and reflect on the truly incredible impact photonics will have on humanity’s future.

polarisation drift caused by fibre optics while allowing for high network uptime.
Sensors winner: Lidar-on- chip, Scantinel Photonics Scantinel X-One is a photonics chip frequency-modulated continuous-wave (FMCW) lidar solution that enables a >300m detection range with direct velocity information. The innovative 1,550nm chip is designed for mass production and will be available to the industry at a competitive price.
Software winner: Frenel Imaging, TPiCore The TPiCore image processing framework allows users to capture additional information from polarimetric thermal sensors. Coupled with a micro- polariser array division of focal plane, the framework enables a single super-resolution image that provides access to
untapped polarimetric data. Software algorithms extract and analyse polarimetric attributes from images captured in bands, enabling the characterisation of targets and scenes.
Test and measurement winner: Persistence Data Mining, Soilytics Persistence Data Mining’s platform uses hyperspectral imaging to map nitrogen, phosphorous, potassium, organic matter and pH to monitor soil health. Imaging soil remotely can offer an attractive alternative to the use of a standard sampling methods. For example, the maps created from hyperspectral data are not affected by inaccuracies inherent in lab processing. The system is also effective in reducing fertiliser over application, which leads to runoff and leaching into ground water. EO
