Extended slow-light field enhancement in positive/negative-index heterostructures
S. Foteinopoulou, J. P. Vigneron
We present a bi-waveguide paradigm composed of joined Positive-Index-Material PIM)/Negative-Index-Material (NIM) slabs, demonstrating ultra-slow light propagation stemming from the…
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…
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…
Search for an optimal light-extracting surface derived from the morphology of a firefly lantern
Annick Bay, Michael Sarrazin, Jean Pol Vigneron
Fireflies lighten up our warm summer evenings. There is more physic behind these little animals than anyone of us could imagine. In this paper we analyze from a physical point of v…
Optimal overlayer inspired by Photuris firefly improves light-extraction efficiency of existing light-emitting diodes
Annick Bay, Nicolas Andre, Michael Sarrazin +4
In this paper the design, fabrication and characterization of a bioinspired overlayer deposited on a GaN LED is described. The purpose of this overlayer is to improve light extract…
Improved light extraction in the bioluminescent lantern of a Photuris firefly (Lampyridae)
Annick Bay, Peter Cloetens, Heikki Suhonen +1
A common problem of light sources emitting from an homogeneous high-refractive index medium into air is the loss of photons by total internal reflection. Bioluminescent organisms,…
