ABSTRACTWe report on the realization and optical properties of a fully evaporated organic microcavity based on LiF-TeOx Distributed Bragg Reflectors and a substituted quinquethiophene as active material. The PL spectrum shows a strong line-width reduction, down to 10 nm, with respect to the bulk spectrum, which is about 110 nm broad. The emission at the mode wavelength shows an enhancement due to the light matter coupling in the optical resonator. The cavity mode shows a splitting for emission angles higher than about 30 degrees which continuously increases with angle up to 99 meV. This feature is observed both in angle resolved PL spectra and in angle resolved reflectance with unpolarized light. A study of angle resolved reflectance with polarized light allows us to attribute this splitting to a polarization effect, rather than to Rabi splitting due to strong coupling in the cavity.

The Ideal

In this chapter we study with the tools developed in Chapter 3 the basic models that are the foundations of light–matter interaction. We start with Rabi dynamics, then consider the optical Bloch equations that add phenomenologically the lifetime of the populations. As decay and pumping are often important, we cover the Lindblad form, a correct, simple and powerful way to describe various dissipation mechanisms. Then we go to a full quantum picture, quantizing also the optical field. We first investigate the simpler coupling of bosons and then culminate with the Jaynes–Cummings model and its solution to the quantum interaction of a two-level system with a cavity mode. Finally, we investigate a broader family of models where the material excitation operators differ from the ideal limits of a Bose and a Fermi field.
