This phenomen can be used to modify the the valence electron energy states of the material taking part into the coupling, and thus modify its chemical properties. This young and still for large parts undiscovered field of study is known as polariton chemistry, and the fundamental research related to it such as this thesis produce valuable information needed for the development of its practical applications.\n\t\n\tThis study follows the emission evolution of a strongly coupled system, when the coupling strength is increased from the strong coupling regime into the ultrastrong coupling regime. The coupled system consists of an ensemble of R6G-dye molecules coupled to an optical resonance mode of Fabry\u2013P\u00e9rot cavity. The Rabi-split energies, propotional to coupling strength, determined from the samples fabricated for this thesis were $0,2518 \\: \\si{\\electronvolt}$, $0,4836 \\: \\si{\\electronvolt}$ and $0,6408 \\: \\si{\\electronvolt}$.
