Abstract: We present the first experimental evidence for the existence of stronglylocalized photonic modes due to random two dimensional fluctuations in thedielectric constant. In one direction, the modes are trapped by ordered Braggreflecting mirrors of a planar, one wavelength long, microcavity. In the cavityplane, they are localized by disorder, which is due to randomness in theposition, composition and sizes of quantum dots located in the anti-node of thecavity. We extend the theory of disorder induced strong localization ofelectron states to optical modes and obtain quantitative agreement with themain experimental observations.
