Dynamics of Electromagnetically Induced Transparency Optical Kerr nonlinearities

摘要: This thesis presents theoretical derivations and experimental demonstrations of Kerr optical nonlinearities their dynamics. The nonlinearity studied is based on electromagnetically induced transparency (EIT), known for having an unusually large cross-phase modulation (XPM) [1]. Also, quantum nondemolition (QND) measurements photon number using the EIT are discussed. We first discuss line shapes in hot atomic vapors both with without buffer gasses, specific case D1 rubidium. Using a Bloch-vector formalism to describe EIT, we derive new expressions describing dynamical evolution rise-time effect. theory dynamics confirmed by experiments rubidium vapor gas. These observations confirm that effect linearly proportional thickness medium inversely width resonance.
