Glass and Glass–Ceramic Photonic Materials for Sensors

Recent developments in sensors are pushing for optimized materials that can increase their usage, bolster their sensitivity and enable new and more efficient transduction mechanisms. We hereby review some of the most relevant applications of glasses and glass-ceramics for photonic sensors considering the recent trends and innovative approaches. This review covers from bulk glasses to thin films and from fiber optics to nanocrystal-based and their applications in sensing.

Optical Quality Resorbable Calcium-Phosphate Glasses for Biophotonic Applications

Recently developed calcium-phosphate glass formulations are proposed in this chapter as a new class of materials for biomedical optics and photonics. The glasses have been designed and carefully prepared in our laboratory to be dissolvable in biological fluids while being optically transparent, mechan-ically reliable both in dry and humid environments, and suitable for both preform extrusion and fiber drawing. Optical fibers have been drawn from these glasses using our custom-made induction h...

Compact Eye-Safe LIDAR Source for Airborne Laser Scanning – The CALIBER Project

A high power, ultra-compact, lightweight, and low cost eye-safe laser source for a Light Detection and Ranging (LIDAR) system is currently under development in the framework of the NATO Science for Peace and Security project “CALIBER”, with the aim to be installed on small Unmanned Aerial Vehicles (UAVs) for surveillance of borders and sensitive areas, with saving in manpower and equipment.

Nonsilica Oxide Glass Fiber Laser Sources: Part I

Nonsilica oxide glasses have been developed and studied for many years as promising alternatives to the most used silica glass for the development of optical fiber lasers with unique features and properties. Depending on the glass former of choice, these glasses can offer very distinctive physical properties if compared to silica-based glasses. With regard to the development of photonic fiber devices, these key properties include low phonon energy, high rare-earth ion solubility, high optical...

Nonsilica Oxide Glass Fiber Laser Sources: Part II

Nonsilica oxide glasses have been developed and studied for many years as promising alternatives to the most used silica glass for the development of optical fiber lasers with unique characteristics. Their main properties and compositions, alongside the optical fiber fabrication principle, have been previously reviewed in part I. This chapter will review the development of optical fiber lasers operating in the infrared wavelength region based on nonsilica glass fiber materials, either phospha...
