Strongly modified spontaneous emission rates in diamond-structured photonic crystals.

چکیده
The spontaneous emission decay dynamics of nanocrystal quantum dots embedded into biotemplated titania photonic crystals with a diamond-based lattice are investigated. Modification of the decay rate of quantum dot emission over wide frequency bandwidths in the visible by the photonic crystals is observed. Frequency-dependent analysis reveals both inhibition and enhancement of emission with a radiative lifetime variation by more than a factor of 10.

Modified Spontaneous Emission Rates in Diamond - Structured Photonic Crystals
The fundamental principle governing radiative transitions is Fermi’s golden rule [1], which states that, ignoring nonradiative pathways, the excited-state decay rate is directly proportional to the photonic density of states (DOS). The photonic DOS is simply the number of electromagnetic modes available for the emitted photons to couple into. This leads to the obvious conclusion that optical em...
متن کاملSpontaneous Emission Spectrum from a Driven Three-Level Atom in a Double-Band Photonic Crystal
Abstract The spontaneous emission spectrum from a driven three-level atom placed inside a double-band photonic crystal has been investigated. We use the model which assumes the upper levels of the atomic transition are coupled via a classical driving field. The transition from one of the upper levels to lower level couples to the modes of the modified reservoir, and the transition from the oth...
متن کاملDiamond-structured photonic crystals.
Certain periodic dielectric structures can prohibit the propagation of light for all directions within a frequency range. These 'photonic crystals' allow researchers to modify the interaction between electromagnetic fields and dielectric media from radio to optical wavelengths. Their technological potential, such as the inhibition of spontaneous emission, enhancement of semiconductor lasers, an...
متن کاملAn experimental study of strongly modified emission in inverse opal photonic crystals
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 ...
متن کاملSpontaneous-emission rates in finite photonic crystals of plane scatterers.
The concept of a plane scatterer that was developed earlier for scalar waves is generalized so that polarization of light is included. Starting from a Lippmann-Schwinger formalism for vector waves, we show that the Green function has to be regularized before T matrices can be defined in a consistent way. After the regularization, optical modes and Green functions are determined exactly for fini...
