Photonics is a key 21st-century technology at the heart of autonomous cars, 5G networks and next-generation medical devices. CSEM has decades of experience in the transfer of several technologies – including nanoscale optical structures, photonics integrated circuits, laser sources, optical instruments for metrology and gas sensing as well as intelligent imaging – to the industrial sector. Our solutions are used in a wide range of domains, including non-invasive health diagnostics, lighting, energy, security, manufacturing, communication, metrology, lidar, quantum science and mobility.

Research and development in Photonics

Our photonics solutions can help you benefit from the power of light. Here are some examples:

Micro- and nano-optics

  • Enabling new functionalities to be added to optoelectronic devices
  • Developing free-form micro-optical components with no restrictions in rotational or translational symmetry, making them a powerful tool for optical designers and engineers
  • Boosting device miniaturization and performance, creating new functionalities, and reducing manufacturing costs
  • Using light-matter interaction with nanostructures to enable unique optical effects used in document security features, for example

Laser sources and laser-based systems

  • Developing versatile and modern tools for machining, polishing, soldering, cutting, measuring, detecting, and identifying compounds
  • Pushing the limits of short pulse laser sources in terms of frequency and amplitude stability, pulse duration, pulse energy, beam quality, compactness, cost, and more
  • System engineering of laser-based instruments for gas sensing, distance measurement, low-phase noise microwave generation, atomic clocks and microwave photonics
  • Laser metrology

Photonic-integrated circuits (PICs)

  • Combining small footprint, scalability, and reduced costs for industrial applications, such as sensing, lidar, telecommunication, metrology, and quantum technologies
  • Focusing on the lithium niobate on insulators (LNOI) platform for PICs that include high-speed modulators, phase shifters, and nonlinear photonics capabilities
  • Offering design, foundry, test, and integration services

Multispectral imaging

  • Developing fast, low-cost systems for use in point-of-care medical, environmental, and industrial applications
  • Combining this approach with machine learning to enable plug and play instrumentation for complex decision making
  • Embedding these processes at the edge enables data privacy, security and ultra-fast processing

Image Sensors

  • Providing state-of-the-art high-speed, high-dynamic range, event-based sensing, and ultra-low-power image

Thierry Dreyfus

Head of Technology

CSEM and Regent share a passion for innovative lighting solutions and products. From the very beginning, we established an excellent relationship based on mutual trust and respect. In turn, this has led to many follow-up collaborations. We have recently completed a project closely related to RUN+ and hopefully, this will soon materialize in another innovative product release from Regent.
