Non-reciprocal optical mirrors based on spatio-temporal acousto-optic modulation
Here, we investigate a scheme to realize free-space isolators and highly non-reciprocal mirrors with weak modulation imparted by an acoustic wave. We propose a strategy to dramatically break time-reversal symmetry by exploiting resonant interactions betwee ...
2018Near-field characterization of Bloch surface waves based 2D optical components
Bloch surface waves (BSWs) are surface electromagnetic modes that propagate at the interface between a multilayer substrate and a homogeneous external medium. The optical field of the surface mode is confined near the surface of the multilayer. This vertic ...
EPFL2017Spatial fringe analysis techniques for multiple phase and phase derivative estimation
Analysis of fringe patterns for the accurate estimation of phase and phase derivatives is of crucial importance in optical interferometry as these quantities provide important information on the physical parameters under study. A wide range of applications ...
EPFL2016Fringe filtering technique based on local signal reconstruction using noise subspace inflation
Pramod Rastogi, Rishikesh Dilip Kulkarni
A noise filtering technique is proposed to filter the fringe pattern recorded in the optical measurement set-up. A single fringe pattern carrying the information on the measurand is treated as a data matrix which can either be complex or real valued. In th ...
2016Versatile High Repetition Rate 2-μm Pulsed Source Based on Wideband Parametric Conversion
Camille Sophie Brès, Adrien Billat, Steevy Joyce Cordette
We report an all-fiber pulsed source based on parametric conversion followed by thulium amplification able to deliver picosecond pulses at a repetition rate selectable between 2 and 5 GHz, of which central wavelength can be freely selected in the 2-μm regi ...
