Laser-based manufacturing of freeform glass micro-optics through topological transformation
Glass has been the material of choice for making optical elements, in large part due to its intrinsic properties: a temperature-dependent viscosity, which enables shaping the material into a broad variety of functional and artistic glassware. Silica glass ...

2023Analytical and Machine Learning Methods for the Complete Safe Coordination of Astrobot Swarms
The recent generations of massive spectroscopic surveys aim at the ray collection from a multitude of cosmological targets in the course of observations. For this purpose, astrobots are used to change the configuration of optical fibers from one observatio ...
EPFL2021System, device and method for quantum correlation measurement with single photon avalanche diode arrays
Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic
A system for photon correlation of an illuminated object and/or a light source, including a light source for illuminating the object or to correlate, an optical system having an object-facing side configured to face the object or the light source and a pro ...
2020Are Photonic Nanojets Achromatic?
Toralf Scharf, Myun Sik Kim, Michail Symeonidis
In this work we study the evolution of the photonic nanojet (PNJ) phenomenon as the ratio of the sphere's diameter over the illumination wavelength changes, for microspheres with diameters from 2 mu m to 100 mu m. We measure the focal point position by usi ...
