(English) The brain is an organ with a large energy budget compared to its volume and weight and constantly requires oxygen-rich blood to meet its metabolic needs. Given this fact, a tool that enables ...
(English) This thesis, mostly experimental, is based on two fundamental pillars: nonlinear interferometers and Optical Coherence Tomography (OCT). Nonlinear interferometers are a class of interferometers ...
(English) Light is a powerful non invasive tool for probing matter down to its fundamental molecular properties. The past three decades saw advent of metallic nanoantennas engineered to concentrate light ...
(English) The fundamental science and technological applications of light-matter interactions on nanometer length scales form the field of study known as nanophotonics. Explorations in nanophotonics ...
(English) Optical metasurfaces established themselves as potential platform for planar and integrated optics. Progress in the material sciences and fabrication process paves the way towards ultra-thin ...
(English) Resolution enhancement in modern optical metrology techniques has been possible due to significant technological improvements. The accurate and precise control of wavelength, bandwidth, and ...
(English) In this work we propose and demonstrate cavity-enhanced polarization rotation to detect magnetic effects in transparent media with greater sensitivity at equal optical disturbance to the atomic ...
(English) This Ph.D. thesis presents research in imaging and optical sensing, exploring novel concepts, and diverse applications. The experimental schemes put forward here are based on simulating specific ...
(English) Nowadays, being able to precisely characterize nanoparticles is of key relevance in a wide range of scenarios. For instance, chemical and pharmaceutical industries often rely in particle-sizing ...
(English) Our ability to confine, guide, and bend light has led to astonishing technological achievements, playing a fundamental role in diverse fields like microscopy, photochemistry, telecommunications ...
