Recently developed, high-efficiency, light-emitting diodes use two-dimensional photonic crystals to enhance the extraction of otherwise internally trapped light and multilayer reflectors to control the direction of light emission. This work describes the characterization of a naturally evolved light-extraction system on the wing scales of a small group of Papilio butterflies. The efficient extraction of fluorescence from these scales is facilitated by a two-dimensional photonic crystal slab… Expand
Controlled fluorescence in a beetle's photonic structure and its sensitivity to environmentally induced changes
Time-resolved fluorescence measurements and optical simulations confirmed that the radiative emission is controlled by a naturally engineered photonic bandgap while the elytra are in the dry state, whereas non-radiative relaxation pathways dominate the emission response of wet elyTra. Expand
Color control of natural fluorescent proteins by photonic crystals.
It is demonstrated that the apparent emission color of the fluorescent protein can be controlled externally by the photonic crystal, and may be extended to control emission rates and complex Förster energy-transfer systems obtained by protein engineering. Expand
Capture and Concentration of Light to a Spot in Plastic Lightguides by Circular Luminophore Arrangements
In this work, it is demonstrated how organic dichroic fluorescent dye molecules embedded in a polymerizable liquid crystal host can be aligned in circular patterns so that sunlight is captured by theExpand
Principles of coherent scattering 3 . 1 Photonic crystals

Improved light extraction in the bioluminescent lantern of a Photuris firefly (Lampyridae).
The most efficient pieces of the lantern structure are the misfit of the external scales and the lowering of the refractive index at the level of the cluster of photocytes, where the bioluminescent production takes place. Expand
Unveiling the nonlinear optical response of Trictenotoma childreni longhorn beetle.
How NLO techniques can complement other more convenient approaches to achieve a more comprehensive understanding of insect scales and integument properties is described. Expand
Bi-functional photonic structure in the Papilio nireus (Papilionidae): modeling by scattering-matrix optical simulations.
The bi-functional optical role of the Papilio nireus is revealed by means of numerical simulations based on the scattering-matrix formalism and results highlight an enhanced fluorescence occurring in the spatial as well as in the frequency domain. Expand
A biological quarter-wave retarder with excellent achromaticity in the visible wavelength region
Animals make use of a wealth of optical physics to control and manipulate light, for example, in creating reflective animal colouration1, 2, 3 and polarized light signals4. Their precise optics oftenExpand
Biologically enabled sub-diffractive focusing.
A biological super-resolving lens to achieve sub-diffractive focusing in the far field by characterizing and using the transmission properties of this valve using the optical eigenmode technique, able to confine light to a tiny spot with unprecedented precision in terms of resolution limit ratio.

Nonlinear optical spectroscopy and two-photon excited fluorescence spectroscopy reveal the excited states of fluorophores embedded in a beetle’s elytra
The role of form anisotropy in the photonic structure, which causes additional tailoring of the beetle’s optical responses, is demonstrated by circularly polarized light and nonlinear optical measurements. Expand


Enhanced coupling to vertical radiation using a two-dimensional photonic crystal in a semiconductor light-emitting diode
Enhanced coupling to vertical radiation is obtained from a light-emitting diode using a two-dimensional photonic crystal that lies entirely inside the upper cladding layer of an asymmetric quantumExpand
Optical probes inside photonic crystals
The spontaneous emission of an atom is not a property of the atom only; it also depends on the local optical surroundings. The simplest demonstration of this effect was provided by the earlyExpand
Fluorescent signaling in parrots.
It remains a mystery whether naturally occurring fluorescence functions as a signal or is a by-product of pigment structure, but here, it is tested. Expand
Fluorescent Enhancement of Signaling in a Mantis Shrimp
Fluorescence has more potential to contribute to color underwater than in terrestrial situations, because the optical properties of water spectrally filter both the incident and the reflected light. Expand
