    • Lasers for Raman spectroscopy in Mars exploration
      Lasers for Raman spectroscopy in Mars exploration     Destination: Mars The ExoMars program has been established by the European Space Agency (ESA) to investigate Martian environment and to demonstrate new technologies that will be necessary in future missions. To meet the programme objectives, ExoMars has foreseen two space missions. First mission, already launched on 14 March 2016, comprised the Trace Gas Orbiter (TGO) and the experimental lander Schiaparelli. The second one includes a rover that will move across the planet drilling up to 2 meters below the surface, and h

    • The future of Silicon Nitride photonic integration technologies
      The future of Silicon Nitride photonic integration technologies Silicon nitride has received a lot of attention during the last ten years, for applications such as bio-photonics, tele/datacom, optical signal processing and sensing. In this talk, firstly an updated review of the state of the art of silicon nitride photonics integration platforms will be provided. Secondly, our developments on a moderate confinement Si3N4 platform in the near-infrared will be presented. Finally, our steps towards establishing a Si3N4 based platform for broadband operation spanning from visible to mid-infrared wavelengths will be introduced.

    • Living Photonics: Monitoring light propagation through cells
      Living Photonics: Monitoring light propagation through cells             Is it possible to confine light through cells? Cells are complex biological entities containing cellular components and barriers with different optical properties. However, in macroscopic point of view, cell layers may be considered as polymeric sheets of some microns with optical continuity and an effective refractive index slightly higher than the surrounding medium. When grown on top of a low refractive index support, this biological layer may act as the core of a biological waveguide, where the surrounding medium and the low refra

    • Custom PDK design process in Synopsys software: S-Matrix Generation using RSoft
      Custom PDK design process in Synopsys software: S-Matrix Generation using RSoft The design of photonic integrated circuits requires the use of flexible design tools to creatively and inexpensively solve new problems. Designers must also be able to create custom PDK models to augment existing foundry PDKs, create new PDKs, or even generate intellectual property (IP). The Synopsys/RSoft design flow meets this need through tight integration between both the circuit and component levels. Advanced numerical methods are used to generate a custom component models that include S-Matrix data and mask layout information. These models can be seamlessly used in a P

    • Innovative Lithography Strategies for Fabrication of Optical Devices
      Innovative Lithography Strategies for Fabrication of Optical Devices Optical devices on nanoscale are nowadays highly requested in both scientific and industrial applications. Raith supports researchers in this field with high-quality technical solutions. Innovative strategies for nanofabrication with electron beam lithography (EBL) have been developed and improved over the past years. In this presentation, we will provide an overview of advanced patterning strategies for optical devices such as photonic crystals, gratings or waveguides. Of course the main focus is on pattern fidelity and dimensional accuracy in such applications. However, increase of throughp

    • Integrated Microwave Photonics
      Integrated Microwave Photonics Microwave Photonics (MWP) is a key technology to interface optical fiber and radiofrequency segments in communication and information networks. Current emerging application scenarios such as 5G and the Internet of things demand agile, compact and low power consumption MWP systems, which can only be realized through photonic integration. In this talk I will present the basics of integrated MWP and report the recent progress reported both in application specific as well as in general purpose integrated MWP.

    • Real-time lidar imaging for applications in autonomous systems and robotics
      Real-time lidar imaging for applications in autonomous systems and robotics There is currently a strong demand for the automation of all types of vehicles, especially terrestrial or maritime. These applications usually include a number of redundant sensors of different capacities and natures, to facilitate decision making by aproaching the complete sensing of the environtment with as much complementarity a spossible. This has sparked interest in the development of commercially viable lidar imaging systems, which are complementary to the most widely accepted imaging modalities, such as conventional 2D imaging and radar sensors. Lidars provide a complementary sensor for

      Novel materials for single photon quantum emitters Solid State sources of Single Photons were proposed by the first time in 2000, both quantum dots (QDs)[1] and nitrogen-vacancy (NV) centers in diamond[2], even if the quantity of basic studies and applications increased very fast for QDs due to the highest growth control, emission efficiency and capabilities of integration in different resonant cavities processed in GaAs. In fact, the fabrication of these cavities (micropillars, microdiscs and photonic crystal structures, mainly) leads to higher repetition rates, high qu
