Abstract

Multiphoton induced reflectivity, a phenomenon related to the electromagnetically induced transparency that was recently discussed in the literature, describes the reflection, by an optical cavity, of a probe field capable of injecting N photons simultaneously into such cavity when it interacts with a two-level atom through an N-photon coupling (atom can only be populated in its excited state through the simultaneous annihilation of N photons in the cavity mode). Such a phenomenon can be applied, for example, in a quantum filter that blocks or selects specific Fock components from the probe field. As the phenomenology of electromagnetically induced transparency and its extensions can be mapped in certain configurations of coupled classical harmonic oscillators, in this project we aim to investigate how to describe the phenomenology of the two-photon induced reflectivity (N = 2) from an analogous system comprising a set of classical parametric oscillators. This mapping can be useful not only for practical device without the necessity of sophisticated technologies required for quantum systems, but also for general scientific dissemination.
