Cascaded Conical Refraction
(Universitat Politècnica de Catalunya / Universitat Autònoma de Barcelona, 2011-07-19)
Master thesis
Open AccessEnglish: After a brief introduction to the conical refraction phenomenon, the formation of transverse intensity patterns by a cascade of biaxial crystals with alignedoptic axes is studied in detail. Up to 2^(N-1) concentric ... -
Chiral Quantum Optics with three-level atoms
(Universitat Politècnica de Catalunya, 2017-07-19)
Master thesis
Open AccessWe study the dissipative dynamics of a three level atom in a cascade configuration driven by two independent lasers and coupled to a semi-infinite waveguide. The coupling to the waveguide is chiral, in the sense that each ... -
