Advancing diagnosis

Optical coherence tomography (OCT) is becoming faster and more effective, allowing the imaging of functional processes in tissue, finds Barbara Stumpp

Printing living tissue

Only two companies supply commercial 3D printing systems based on two-photon polymerisation, which can create structures smaller than living cells. Greg Blackman speaks to Denis Barbier from Microlight3D

Measure for measure

Keely Portway looks at some of the latest advances in light-based test and measurement techniques

Biological imaging reaches new depths

Shaping light wavefronts is improving many areas of microscopy – and is enabling Nobel Prize winner Eric Betzig’s most important work yet, finds Andy Extance

Swiss photonics is pushing innovation

Andreas Ettemeyer, NTB Interstate University of Applied Sciences, Buchs, and member of the EOS board, expresses concerns about discussions to merge photonics with microelectronics within European Union funding

Optics for 5G

Prism technology that’s now a major part of optical communications is finding its way into next-generation lidar systems

Chilling out

Barbara Stumpp rounds up the latest methods of cooling laser diodes efficiently

The dividend of the spectrum

Imaging spectroscopy offers a powerful way to understand this world and others, and optical innovations are enhancing its capabilities, finds Andy Extance

Breaking into aviation

A project called Saphyr developing photonic technologies for aeronautics is underway, with the aim of having demonstrators at the Le Bourget Air Show in Paris in June 2019. Alain Fontaine, president of French consulting company Pegase and Saphyr coordinator, argues that photonics should play a much greater role in aviation

Healing properties of light

Light therapies are coming to the fore to treat a huge range of medical conditions, from neonatal jaundice to dementia, as Keely Portway finds out

Small is beautiful

As optics get smaller, simulation software is having to turn to new techniques to model optical systems, as Barbara Stumpp finds out

The rise and rise of VCSELs

VCSELs are known for their size, reliability, volume scalability and cost effectiveness. With more industries catching on to their potential, it’s no wonder the VCSEL market is forecast to be $3.1bn in four years, says Keely Portway

Astronomy on a chip

Professor Dr Martin Roth, at research centre Innofspec Potsdam, discusses the role that fibre Bragg gratings and other photonics components could play in transforming astronomy

Lighting up the road

Various lidar companies are finding ways to meet the huge challenges automotive applications present. Jessica Rowbury discovers Luminar’s approach, and decisions made in designing their system

Four reasons teams fail to innovate

In a follow-up to her piece in our last issue, Liz Gerrish, technical programme manager and senior optical engineer at Wilcox Industries, provides further leadership perspective from being a woman in STEM

Adding up in Aachen

Matthew Dale reports from the AKL International Laser Technology Congress, in Aachen, Germany, in May, where the potential for additive manufacturing in series production was high on the agenda

Virtual design

A look at the latest optical modelling programs and their application in the development of self-driving cars

Reflecting on mirrors

A look at the use of optical mirrors in space telescopes, and a round-up of the commercial offerings available for every application

A shining celebration

On 16 May, the first International Day of Light celebrated the role of light and related technologies in science, art, education and sustainable development. Here we round up some of what occurred the day

Fine tuning

A laser-based gas analyser that employs novel optical parametric oscillator (OPO) technology was a finalist in this year’s SPIE Prism Awards

Making flying safer

Optical explosive detection is set to help remove restrictions on the liquids airline passengers can carry on, finds Andy Extance

Unveiling the Cosmos

Dr Aris Kouris, executive director of sales at Optical Surfaces, was asked about the latest challenges and trends in modern astronomy

Spectral signature

A new business unit will allow TruTag Technologies to better serve additional markets that have emerged from its hyperspectral imaging technology, Jessica Rowbury finds

Scaling spectroscopy

Matthew Dale discovers how scaling spectrometers down to the chip level enables them to be mass-produced in standard MEMS foundries, making spectroscopy more affordable for various new applications

Taking the heat off PICs

Shrinking optoelectronic components and combining them with silicon devices requires careful consideration of thermal management, finds Andy Extance
