From photonic dots to photonic crystals-Status and potential of semiconductor systems with taylored photonic states

We review the status of current realizations of photonic band gap systems for the optical wavelength range. Furthermore results of an approach developed by us based on the controlled combination of elementary cells with 3D photonic confinement (photonic dots) will be presented. We have investigated size confinement and interaction effects of optical modes in InGaAs/(Al)GaAs microcavities with dimensional optical confinement (photonic dots).
