Large field enhancement obtained by combining Fabry-Perot resonance and Rayleigh anomaly in photonic crystal slabs
Kokou B. Dossou
By applying the properties of Fabry-Perot resonance and Rayleigh anomaly, we have shown that a photonic crystal slab can scatter the light from an incident plane wave into a diffra…
Modal formulation for diffraction by absorbing photonic crystal slabs
Kokou B. Dossou, Lindsay C. Botten, Ara A. Asatryan +5
A finite element-based modal formulation of diffraction of a plane wave by an absorbing photonic crystal slab of arbitrary geometry is developed for photovoltaic applications. The…
Doppler shift generated by a moving diffraction grating under incidence by polychromatic diffuse light
Kokou B. Dossou
We consider the spectral response of moving diffraction gratings, in which the incident light extends over a broad angular range and where the diffracted light is observed from a s…
Total absorption of visible light in ultra-thin weakly-absorbing semiconductor gratings
Björn C. P. Sturmberg, Teck K. Chong, Duk-Yong Choi +7
The perfect absorption of light in subwavelength thickness layers generally relies on exotic materials, metamaterials or thick metallic gratings. Here we demonstrate that total lig…
