Interacting with and Generating Light

It is a long-standing goal to create light with unique quantum properties such as squeezing and entanglement. We propose the generation of quantum light using free-electron interactions, going beyond their already ubiquitous use in generating classical light. This concept is motivated by developments in electron microscopy, which recently demonstrated quantum free-electron interactions with light in photonic cavities. Such electron microscopes provide platforms for shaping quantum states of light through a judicious choice of the input light and electron states. Specifically, we show how electron energy combs implement photon displacement operations, creating displaced-Fock and displaced-squeezed states. We develop the theory for consecutive electron-cavity interactions with a common cavity and show how to generate any target Fock state. Looking forward, exploiting the degrees of freedom of electrons, light, and their interaction may achieve complete control over the quantum state of the generated light, leading to novel light statistics and correlations.

The generation of squeezed light across dual octaves with single-mode multichannel nonlinear waveguides exhibits dynamic behavior. In this study, we examine the impact of coherent state initialization, channel interaction, nonlinearity strength, and inter-channel interaction on the generation of squeezed light over several channels. The findings demonstrate that the process of coherent state initialization and the addition of channel interaction significantly enhance the amount of squeezing, hence emphasizing their critical role in the optimization of squeezed light generation. Additionally, an occurrence of squeezing that is not dependent on nonlinearity is observed within a limited range of parameters. This presents opportunities for generating squeezed light in dual-octave systems with many channels.

An analysis is made of the influence of third harmonic generation and parametric interaction on twophoton coherent effects which occur during propagation of high-power light pulses through resonant media. It is shown that third harmonic pulses can be generated in this way.
