Abstract

We have observed strongly modified spontaneous-emission spectra from laser dye in photonic crystals made of inverse opals in titania $({\mathrm{TiO}}_{2}).$ We identify stop bands with large relative widths of $15%,$ comparable to the dyes' emission spectrum, and $75%$ attenuation of the emission strength. For a wide range of angles, two stop bands are simultaneously manifested; their angle-dependent frequencies display an avoided crossing that is corroborated by reflectivity experiments. The edges of the stop bands agree well with band-structure calculations, but differ from simple Bragg diffraction as a result of multiple wave coupling. The strongly reduced dispersion of the Bloch modes likely causes a significant change in the density of states.

An experimental study of strongly modified emission in inverse opal photonic crystals

A. Femius Koenderink, Lydia Bechger, Ad Lagendijk +1 more

We present the first experiments that demonstrate strong angle-independent modification of spontaneous emission spectra from laser dyes in photonic crystals, made of inverse opals in titania. We show that both the fluorescence quantum efficiency and weak disorder play a key role in interpreting the experimental data. We compare the angle-independent emission spectra of dye in photonic crystals with spectra from such crystals with much smaller lattice spacings, for which emission is in the long wavelength limit. The ratio of emission power spectra shows inhibition of emission up to a factor ∼ 5 over a large bandwidth of 13% of the first order Bragg resonance frequency. The inhibition shifts to increasing wavelength with the lattice parameter, confirming the photonic nature of the phenomenon. The center frequency and bandwidth of the inhibition agree with the calculated total density of states, but the measured inhibition of the vacuum fluctuations is much larger. This result is confirmed by experiments using different dyes. We likely probe the strongly modulated local photonic density of states, due to the spatially nonuniform distribution of dye molecules over the unit cell.

Broadband Fivefold Reduction of Vacuum Fluctuations Probed by Dyes in Photonic Crystals

A. Femius Koenderink, Lydia Bechger, Henry P. Schriemer +2 more

We observed for the first time a strong angle-independent modification of spontaneous emission spectra from laser dyes in photonic crystals, made of inverse opals in titania. Comparison with spectra from such crystals with much smaller lattice spacing, for which emission is in the long wavelength limit, reveals inhibition of emission up to a factor approximately 5 over a large bandwidth of 13% of the first order Bragg resonance frequency. The center frequency and bandwidth of the inhibition agree with calculated total density of states, while the measured inhibition of vacuum fluctuations is much larger. Because of the specific location of the dye molecules, we likely probe the strongly modulated local photonic density of states.

Modification of the spontaneous emission of dye molecules embedded in artificial opals exhibiting stop bands in the visible range is observed.Molecules embedded in artificial opals show dips in spontaneous emission spectra and modified fluorescence decay kinetics.Results are interpreted in terms of redistribution of the photon density of states.Effects of the multiple reabsorption and reemission of fluorescence photons and interaction of dye molecules with the silica surface are discussed.

Quantitative analysis of directional spontaneous emission spectra from light sources in photonic crystals

Ivan S. Nikolaev, Peter Lodahl, Willem L. Vos

We have performed angle-resolved measurements of spontaneous-emission spectra from laser dyes and quantum dots in opal and inverse opal photonic crystals. Pronounced directional dependencies of the emission spectra are observed: angular ranges of strongly reduced emission adjoin with angular ranges of enhanced emission. It appears that emission from embedded light sources is affected both by the periodicity and by the structural imperfections of the crystals: the photons are Bragg diffracted by lattice planes and scattered by unavoidable structural disorder. Using a model comprising diffuse light transport and photonic band structure, we quantitatively explain the directional emission spectra. This work provides detailed understanding of the transport of spontaneously emitted light in real photonic crystals, which is essential in the interpretation of quantum optics in photonic-band-gap crystals and for applications wherein directional emission and total emission power are controlled.

Emission in a SnS2 inverted opaline photonic crystal

Sergei G Romanov, Torsten Maka, Clivia Marfa Sotomayor Torres +2 more

The photoluminescence of a dye embedded in the three-dimensional SnS2 inverted opal has been studied. Changes of the emission spectrum compared with the free-space dye emission was observed in the stop-band frequency range in accord with reflectance/transmission spectra of this photonic crystal. The angular-dependent component, due to the Bragg stop band, and the angular-independent component, which is, possibly, related to the minimum in the density of photon states, have been distinguished in the dye emission spectrum.

Spontaneous emission of laser dye molecules in synthetic opals under conditions of low dielectric contrast

Spontaneous emission of laser dye molecules (rhodamine 6G and pironin G) embedded into pores of synthetic opal photonic crystals is studied in the spectral region of 520-650 nm.It is ascertained that the emission spectra are greatly dependent on the photonic stop-band position and the spectral distribution of photon density of states.A dependence of spectral position of the emission band from the dielectric contrast is found.
