📢 Announcing our next Topical Meeting at EOSAM 2024: TOM6 - Optical Materials Optical materials are vital for multiple current and future industrial applications and continuously generate important investigations with major scientific and technological challenges. For example, in many fields of photonics, the fabrication and structuring of thin films at the micro and nanometric scale is essential, such as for optical nanoantennas and metasurfaces. Simple and easy-to-implement techniques such as the sol-gel processes and solution-based synthesis, and costly ones such as epitaxy, MOVPE, laser ablation (PLD), and rf sputtering are commonly used to produce different optical materials. Correlation between the material optical characteristics and its structural, compositional, and morphological properties is of great importance. Eventually, there are significant needs to develop innovative techniques for the fabrication of new materials, as well as to develop simple and efficient characterization techniques. These needs have given rise to multidisciplinary research with the ambition to provide optical materials and devices from an approach linking the desired performances to the nano and micro structure.

The challenges of optical data retrieval!

What's the real difference between a CD, DVD, and Blu-ray disk? It all comes down to the size of the pits used to convey information and the wavelength of the laser used to read them Shorter wavelengths can be focused to smaller spots, letting a violet laser read the densely packed pits on a Blu-ray disk that a red laser couldn't read This same principle is what has led many laser systems to move to shorter wavelengths to improve precision for everything from laser materials processing to medical applications But moving to short UV wavelengths comes with its own set of unique challenges.

EXALOS, the world’s leading manufacturer of Superluminescent Light-Emitting Diodes (SLEDs), has been selected as a finalist for the prestigious SPIE Prism Award 2025, which will be handed out at the upcoming SPIE Photonics West in January next year. The annual event, which will be celebrating its 17th year, recognizes commercialized innovation in photonics, honoring companies that are bringing transformative products to market. Among the distinguished finalists, EXALOS is the only company from Switzerland. The nominated, advanced 14-pin Butterfly (BTF) module emits an optical spectrum with 3dB bandwidth of 33 nm around a center wavelength of 1549 nm. The output is collimated into three output beams that are propagating through an optical circulator before being focused into an array of three PM output fibers. Efficient beam collimation, low-loss beam propagation on the optical bench in combination with high-efficiency coupling to the PM output fibers results in output power values of around 1.0 mW per fiber channel at low drive currents of only 150 mA. Thanks to the micro-optical integration of the three closed-loop FOGs, the innovative 14-pin BTF module, allows the creation of products with a less external components and a significantly reduced footprint.

Presentation alert @ #ECIO2024 European Conference on Integrated Optics (ECIO) Tomorrow (Tuesday, 18/June/2024: 4:30pm - 6:00pm), in the #Programmable #Photonics and #MEMS track, we are presenting our recent work on monolithic integration of piezo-MEMS with photonics. The presentation is titled "Photonic Integrated Piezo-MEMS (Pip-MEMS) Device for 1D Beam Scanning". For the first time, we present #sputter-deposited piezo-electric #PZT on SiN waveguide for optical beam forming applications. We show a single-axis steer of 6.6 deg, which is modest, yet scalable. However, the device requires <0.2 mW of power, which is abysmal compared to other steering platforms. Thanks to Venkatachalam P and Daniel Yumnam for this nice demonstration. Thanks to Sushma Gali for her visible light characterisation expertise. More details in this thread on the achievement to follow here after the presentation.

📢 We are excited to announce our next Topical Meeting at EOSAM 2024: TOM2 - Frontiers in Optical Metrology! This Topical Meeting is designed as a forum for application-oriented basic and applied optical metrology techniques. This includes basic methods, fundamental limits, measurement techniques and their applications, foundations of applied metrology as well as future trends and topics. As optical metrology methods are generally non-contact, non-destructive, fast, reliable, and have high precision and can sometimes even be used in a rugged environment, they lend themselves very much to industrial applications such as process development, in-line processing, and quality control. However, since industrial demands are sometimes very specific and increasingly challenging, there is a continuous requirement for more ruggedness, higher resolution, and faster measurement and evaluation to name only a few constraints. This situation not only calls for evolutionary improvement but also asks for new ideas or even new paradigms. Besides developing new methods and paradigms, rigorous modeling and simulations also deserve due attention, especially in the emerging fields of computational metrology. Finally, an assessment of the absolute performance in terms of resolution and measurement uncertainty stresses the role of traceability to internationally recognized primary metrology standards. These, in turn, translate into calibration efforts to obtain metrically valid and consistent results. Invited speakers for this TOM: - Martin Oheim: Near-interface sensing, imaging and nanometrology using smart surfaces. - Robert Kuschmierz: Measuring and compensating the optical transfer functions of flexible imaging waveguides for lensless endoscopy - Lisa Miccio: In-flow tomographic imaging for single cells analysis - Manuela T.
