Measurement and modeling of microlenses fabricated on single-photon avalanche diode arrays for fill factor recovery
Edoardo Charbon, Juan Mata Pavia, Martin Wolf
Single-photon avalanche diode (SPAD) imagers typically have a relatively low fil factor, i.e. a low proportion of the pixel's surface is light sensitive, due to in-pixel circuitry. We present a microlens array fabricated on a 128x128 single-photon avalanch ...
Optical Soc Amer2014Minimizing distortion and enlarging group delay in Brillouin slow light systems by gain profile optimization
Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Li Zhang
Optimal gain spectra minimizing distortion and enhancing delaying efficiency in linear slow light systems are predicted and experimentally validated by shaping the gain spectral profile in a Brillouin fiber amplifier. ...
Optical Society of America2014Further study on iterative control loop for aberration correction in imaging systems with single mode fibre aperture
An iterative control system was designed for compensation of wavefront aberration utilizing a micromachined deformable mirror through simulated annealing algorithm. 37 elements within a deformable mirror are controlled individually in a closed-loop to maxi ...
Natl Inst Optoelectronics2013Experimental and theoretical study of the Gouy phase anomaly of light in the focus of microlenses
Hans Peter Herzig, Toralf Scharf, Myun Sik Kim, Ali Naqavi
We report on the Gouy phase anomaly of light in the focus of cylindrical and spherical microlenses. The prime subject of our study concerns a discussion of how the very small size of microlenses affects the phase properties of light in their foci. We put e ...
Institute of Physics (IoP) and Deutsche Physikalische Gesellschaft2013Three-dimensional Super-resolution Optical Fluctuation Imaging
Theo Lasser, Marcel Leutenegger, Stefan Geissbühler, Noelia Laura Bocchio, Corinne Berclaz
Super-resolution optical fluctuation imaging (SOFI) achieves three-dimensional super-resolution by computing higher-order spatio-temporal cross-cumulants of stochastically blink-ing fluorophores. In contrast to localization microscopy, SOFI is compatible w ...
