Summary on Grant Application Form |
|
The properties of photons in semiconductors can be tailored by the use of layered dielectric structures, in which both the photon band structure and the coupling to exciton states are altered. The first aim of the proposed programme is the development of a realistic theoretical model for the optical properties of such layered structures, including the effects of excitonic absorption. This will be an important input to a theoretical and experimental study of the modified photonic characteristics. Various types of behaviour will be investigated including: 1) the modification of Rabi splitting in microcavities by electric and magnetic fields. 2) Coherent photonic coupling between degenerate exciton states in spatially separated quantum wells. 3) Interactions with photon modes in weakly coupled double micro-cavity structures. 4) The effects of photonic minibands in 'superlattices' of coupled microcavities.
