One of the most profound phenomena of quantum optics is the reduction of quantum fluctuations in the electromagnetic field, i.e., the existence of squeezed states of light. The approaches to create these non-classical states have commonly relied on large systems, such as nonlinear crystals and atomic vapors. However, recent experiments have shown the ability of microscopic entities to obtain squeezed light with the prospect of making quantum integrated devices with a further control on the squeezing mechanism. Among such sources of non-classical light, the most elementary one consists of a quantum emitter driven by a laser field near resonance. In this theoretical work we investigate the generation of squeezed light with a quantum emitter coupled to an nanostructure. We find that nano-architectures strongly modify the creation of squeezed light. In the far field, we observe that squeezing can be significantly boosted by suitable systems. Moreover, the physical conditions for reducing quantum fluctuations are strongly relaxed with respect to free space. Finally, we analyze the behaviour of squeezed light in the near field, opening the pathway to its manipulation at the nanoscale.
