Titel: Propagation of a photon in an optical waveguide with multiple chirally coupled emitters

Abtract: In this thesis a photon propagating in a 1D waveguide with multiple chirally coupled emitters is investigated. A general transfer matrix for the multiple emitters is deduced. Based on this transfer matrix, numerical solutions for the reflectance and transmitance are plotted and compared with nonchiral systems. It is found, that the chiral systems are much more prone to loss, which increases with the difference between the coupling to the fields propagating in the left and right directions. With the strong coupling the chiral systems has a smaller photonic band gap than the nonchiral system.
