Naturally occurring fluorescence in transparent insect wings
Sébastien R. Mouchet, Charlotte Verstraete, Bojana Bokic +8
In spite of the crucial role it is believed to play in nature, fluorescence in natural organisms remains under-investigated from optical, chemical and biological perspectives. One…
Genetic-algorithm-aided ultra-broadband perfect absorbers using plasmonic metamaterials
Alexandre Mayer, Hai Bi, Sarah Griesse-Nascimento +5
Complete absorption of electromagnetic waves is paramount in today's applications, ranging from photovoltaics to cross-talk prevention into sensitive devices. In this context, we u…
Towards an experimental proof of superhydrophobicity enhanced by quantum fluctuations freezing on a broadband-absorber metamaterial
M. Sarrazin, I. Septembre, A. Hendrickx +9
Previous theoretical works suggested that superhydrophobicity could be enhanced through partial inhibition of the quantum vacuum modes at the surface of a broadband-absorber metama…
Non-linear optical spectroscopy and two-photon excited fluorescence spectroscopy reveal the excited states of fluorophores embedded in beetle's elytra
Sébastien R. Mouchet, Charlotte Verstraete, Dimitrije Mara +8
Upon illumination by ultraviolet light, many animal species emit light through fluorescence processes arising from fluorophores embedded within their biological tissues. Fluorescen…
Quantum vacuum photon modes and repulsive Lifshitz-van der Waals interactions
Louis Dellieu, Olivier Deparis, Jerome Muller +2
The bridge between quantum vacuum photon modes and properties of patterned surfaces is currently being established on solid theoretical grounds. Based on these foundations, the man…
Quantum vacuum photon-modes and superhydrophobicity
Louis Dellieu, Olivier Deparis, Jerome Muller +1
Nanostructures are commonly used for developing superhydrophobic surfaces. However, available wetting theoretical models ignore the effect of vacuum photon-modes alteration on van…
Do CVD grown graphene films have antibacterial activity on metallic substrates?
Louis Dellieu, Emeline Lawarée, Nicolas Reckinger +6
Accurate assessment of the antibacterial activity of graphene requires consideration of both the graphene fabrication method and, for supported films, the properties of the substra…
A two-in-one superhydrophobic and anti-reflective nanodevice in the grey cicada (Hemiptera)
Louis Dellieu, Michael Sarrazin, Priscilla Simonis +2
Two separated levels of functionality are identified in the nanostructure which covers the wings of the grey cicada (Hemiptera). The upper level is responsib…
Plasmon hybridization in pyramidal metamaterials: a route towards ultra-broadband absorption
Michael Lobet, Mercy Lard, Michael Sarrazin +2
Pyramidal metamaterials are currently developed for ultra-broadband absorbers. They consist of periodic arrays of alternating metal/dielectric layers forming truncated square-based…
Nanoarchitecture in the black wings of Troides magellanus: a natural case of absorption enhancement in photonic materials
Aline Herman, Cedric Vandenbem, Olivier Deparis +2
The birdwings butterfly Troides magellanus possesses interesting properties for light and thermal radiation management. The black wings of the male exhibit strong (98%) absorption…
First-principle calculation of solar cell efficiency under incoherent illumination
Michael Sarrazin, Aline Herman, Olivier Deparis
Because of the temporal incoherence of sunlight, solar cells efficiency should depend on the degree of coherence of the incident light. However, numerical computation methods, whic…
The fundamental problem of treating light incoherence in photovoltaics and its practical consequences
Aline Herman, Michael Sarrazin, Olivier Deparis
The incoherence of sunlight has long been suspected to have an impact on solar cell energy conversion efficiency, although the extent of this is unclear. Existing computational met…
Influence of the pattern shape on the photonic efficiency of front-side periodically patterned ultrathin crystalline silicon solar cells
Aline Herman, Christos Trompoukis, Valerie Depauw +2
Patterning the front side of an ultra-thin crystalline silicon (c Si) solar cell helps keeping the energy conversion efficiency high by compensating for the light absorption losses…
