Observation of Spatial Fluctuations of the Local Density of States in Random Photonic Media
Observation of Spatial Fluctuations of the Local Density of States in Random Photonic Media
We experimentally study spatial fluctuations of the local density of states (LDOS) inside three-dimensional random photonic media. The LDOS is probed at many positions inside random photonic media by measuring emission rates of a large number of individual fluorescent nanospheres. The emission rates are observed to fluctuate spatially, and the …
