Impedance-controlled Laser Dynamics in Near-Zero Index Media
Adrien Debacq, Andrei V. Lavrinenko, Elizaveta Semenova +2
Near-zero-index (NZI) media have been explored for controlling spontaneous emission, but their impact on stimulated emission and lasing properties remains unexplored within their d…
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…
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…
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…
