DOPS Annual Meeting 2021 November 17

Get ready for the in-person optics and photonics event of 2021 in Denmark

On 17 November 2021, DOPS and Centre of Applied Photonics are pleased to invite you to an intense one day event with key speakers from the danish optics and photonics community and industry. The day will include plenty of opportunities to network and catch up and will conclude with a dinner event at the excellent IDA restaurant.

In order to ensure we comply with regulations around limited gatherings,  the number of attendees will be limited and take place in the large conference hall of IDA huset to allow for plenty of space. The venue is located conveniently in central Copenhagen at IDA Huset Kalvebod Brygge 31-33, a short walk from the central station.

Notice! – Corona Pas Required

It is required to show a valid corona pas upon arrival to the conference.

Henrik Mertz – Granting your business access to photonics expertise
Head of Department of RoadSensors & Photonics – FORCE Technology.

Centre of Applied Photonics (CAF) is a hub for innovation, granting Danish businesses access to Danish and European expertise within photonics. The Centre’s goal is to ensure that the potential for growth that lies in the latest photonics technology is fully leveraged.

The Photonics department at FORCE Technology has a long and extensive experience in developing photonics products such as optical sensors, imaging systems, illumination systems and fluorescence systems. The development and production of photonics products inevitably encounter problems during the process. We can assist you in identifying the cause and preparing suggestions for solutions.

We grant start-ups, spin-outs and SMEs access to various facilities, services, and demonstration projects that support photonics product development and accelerates the technological readiness level.

Francesco Da Ros – Machine learning & photonics: a symbiotic relationship
Senior researcher, Villum Young Investigator – DTU Fotonik

The popularity of machine learning (ML) and deep learning tools has been booming over the past few years, including their application to problems in the fields of optics and photonics. In this talk, I will address two questions: (i) what benefits does ML bring to photonics? (ii) how can photonics benefit ML? Starting with (i), I will review some of our recent efforts and provide examples of successful applications of ML to the characterization of photonic devices, design, and modeling of an optical subsystem, and full end-to-end optical communication system optimization. A key challenge currently limiting ML techniques is the availability of computing power. This is directly related to the energy-consumption scaling of the electronics-based von Neumann-based computing architectures used as hardware for ML algorithms. Changing perspective then, whereas ML tools can advance the state-of-the-art in photonics, photonics can improve ML. Photonics can provide an extremely promising hardware platform for implementing the high-energy consuming ML algorithms currently relying on digital electronics. Along these lines, I will discuss a few examples of optoelectronics hardware able to solve specific ML tasks.

– Advanced Optics by Nanostructures in Consumer Electronics
Founder, Executive VP Mastering – NIL Technology

NIL Technology (NILT), is an optical solutions company designing, developing, and manufacturing optical elements and components using high-precision nanoscale features. NILT creates competitive advantages with flat optics in optical applications for 3D sensing, consumer electronics, machine vision, autonomous vehicles, telecommunication, and AR/VR/MR displays; all solutions made by diffractive (DOE) and meta (MOE) optics.

Nicolas Volet – Integrated photonics with mature technology platforms
Founder and CTO – UV Medico
Assistant professor – AU Engineering

Applications of laser-related technologies generally require close control over a large set of physical performance, such as the power, wavelength and polarization of the emitted light, or the modulation capabilities, the spectral purity and tunability of the device. Deployment of these technologies out of the lab also involves studies of their costs, packaging and reliability. In this talk, specific examples will be discussed where material systems with optimal properties were combined to demonstrate optoelectronic devices with unprecedented performance or exhibiting new physical phenomena.

Tom André Jos Vosch – DNA stabilized AgNCs for anti-Stokes fluorescence microscopy
Associate Professor – Nano-Science Center, Department of Chemistry, University of Copenhagen

DNA stabilized silver nanoclusters (DNA-AgNC) are a relatively new class of emitters. What makes them interesting are the genetic programmability of the AgNC that is stabilized by the DNA strands. Some DNA-AgNC also have some unusual properties e.g. high fluorescence quantum yield in the NIR region and the ability to generate bright anti-Stokes fluorescence.
