🔬🌟 Exciting Research on Nonparaxial Imaging with Laser-Manufactured Photonic Elements! 🌟🔬 In a recent breakthrough, we explored the fascinating world of structured light – electromagnetic waves characterized by strong spatial variations in amplitude, phase, and polarization. Our study delves into the generation and utilization of nonparaxial terahertz (THz) light, specifically in the form of Airy, Bessel, and Gaussian beams. 🔍 Key Findings: Compact Generation: By leveraging silicon diffractive optics prepared through femtosecond laser ablation technology, we compactly generated structured nonparaxial THz light. This breakthrough opens up exciting possibilities for practical applications. Elongated Focal Zones: Unlike conventional paraxial methods, our approach allows us to create non-diffracting Airy beams without the need for additional lenses. These beams exhibit elongated focal zones, making them ideal for imaging tasks. Applications Galore: We demonstrated the use of these beams in imaging objects partially obscured by opaque materials. From controlled obstacle visualization to imaging stacked graphene layers, our technique showcases the potential for quality assessment of 2D materials. 🔬 Ongoing Research: We’re currently designing, fabricating, testing, and comparing various photonic elements manufactured using high-power laser ablation on silicon substrates. Our goal extends beyond structured nonparaxial illumination – we aim to harness this photonics for light collection in single-pixel nonparaxial imaging systems. Stay tuned for more exciting developments in the world of photonics! 🚀🔍 #Photonics #Research #StructuredLight #Terahertz #Innovation https://lnkd.in/dMnMD9tF

We're thrilled to share our latest research on enhancing the performance of colloidal nanocrystals (NCs) in optoelectronic applications, particularly within the infrared spectrum. Our study, "Shaping the Infrared Luminescence of Colloidal Nanocrystals Using a Dielectric Microcavity," has been published! This research focuses on the innovative use of HgTe/CdS core-shell NCs integrated into a specially designed dielectric mirror cavity. This approach allows us to overcome the challenges posed by metallic metasurfaces, which typically suffer from significant optical losses and low-quality factors. This advancement represents a significant step forward in developing cost-effective alternatives to existing technologies and opens new possibilities for integrating NCs in infrared-based applications. We're excited about the potential impact of our findings and look forward to exploring the capabilities of these innovative systems further. #Nanotechnology #Photonics #Optoelectronics #Innovation #Research #Science

As devices become increasingly miniaturized, precise local characterization of thin films is essential. Ellipsometry, with its non-contact, high-resolution capabilities, is vital for measuring film thickness and refractive indices down to 1 angstrom.

📢 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.
