Abstract

In this paper, we report on the space selective optical switching and detailed lineshape analysis of m-resonances in a PM formed from two dielectric spherical microcavities with CdTe nanocrystals, which allow us to propose a new concept of a multi-channel, wavelength tunable delaying optical device. A layer-by-layer deposition technique provides controllable coating of the latex microspheres (3 mum in diameter) with a shell of close-packed nanocrystals of approximately 4 nm in size
