We investigate a resonant photodiode transferred onto a gold mirror. This comprises a
backside dielectric subwavelength periodic structure and an absorbing region as thin as 90 …

We recently demonstrated orders of magnitude enhancement of two-photon absorption
(2PA) in direct gap semiconductors due to intermediate state resonance enhancement for …

We investigate infrared detection at room temperature using non-degenerate two-photon
absorption in a nanostructured indium phosphide photodiode. We designed the detector …

This letter is on the response of gallium arsenide pin diodes to sub-bandgap photons (1.55 μ
m). We investigate the various regimes of sub-bandgap operation by using different light …

GaAs-based pin 850 nm infrared photodetectors with a narrow bandpass characteristic were
successfully fabricated and demonstrated by epitaxial growth technology. The photo to dark …

We investigate a full-dielectric guided mode resonant photodiode. It has been designed to
enhance the absorption by excitation of several resonances in the SWIR domain. The device …

Les nano-antennes sont des composants nanostructurés capables de concentrer la lumière
dans des volumes sub-longueur d'onde, exaltant le champ électrique selon plusieurs ordres …

Trapping/absorption of light in metallic micro/nano-structures on a dielectric-interspaced
metal layer were widely studied, but discrepancies in results suggests uncertainty in its …

We introduce a 3-step method to optimise a nanostructured photodetector for infrared
sensing through non degenerated two-photon absorption (NDTPA). First, the nanostructure …

Mes travaux de thèses portent sur l'étude de la photodetection infrarouge par processus
d'absorption à deux photons non-dégénérés (NDTPA) dans des diodes nanostructurées à …
