High Gain Spatial Photon Correlations

Bachelor thesis | Natuurkunde (BSc)

Spontaneous parametric down-conversion is a non-linear optical process mediated by a crystal where an incident photon is converted into two or more outgoing photons. The theory describing parametric down-conversion is studied; multi-photon correlations in a spatial basis and orbital angular momentum basis are studied theoretically and experimentally. For high intensity pump fields multiple photon pairs can be created. This is investigated experimentally and by simulation. Theory is developed to describe orbital angular momentum for multiple photon pairs and is applied to double photon pairs. Progress is made to differentiate between spontaneous and stimulated double photon pair emissions.
