Down Converter Device Combining Rare-Earth Doped Thin Layer and Photonic Crystal for c-Si Based Solar Cell
Thierry Deschamps, Emmanuel Drouard, Romain Peretti +7
The aim of the study is to develop ultra-compact structures enabling an efficient conversion of single high energy photon (UV) to two lower energy photons (IR). The proposed struct…
Absorption control in pseudodisordered photonic-crystal thin film
Romain Peretti, Guillaume Gomard, Loïc Lalouat +2
The positive effects of various perturbations introduced in a bidimensional photonic-crystal patterned membrane on its integrated absorption are investigated numerically and theore…
Revisiting literature observations on photodarkening in Yb3+doped fiber considering the possible presence of Tm impurities
Romain Peretti, Cedric Gonnet, Anne-Marie Jurdyc
Ytterbium (Yb) doped fiber lasers are known to be affected by the creation of color centers during lasing (socalled photodarkening (PD)). In a previous work, this defect creation w…
Modal approach for tailoring the absorption in a photonic crystal membrane
Romain Peretti, Guillaume Gomard, Christian Seassal +2
In this paper, we propose a method for tailoring the absorption in a photonic crystal membrane. For that purpose, we first applied Time Domain Coupled Mode Theory to such a subwave…
