“…Hence, the adjacent medium on the metal surface is changed from water to the microbubble. The controlling intensity is much smaller than that in the previous all-optical tuning method 4,48,49 . The large index variation of |Δn|=0.333 greatly changes the phase difference (especially k 0 n eff ×s x ) of the emission light from the two nanogroove antennas based on Eq.…”

Owing to weak light-matter interactions in natural materials, it is difficult to dynamically tune and switch emission polarization states of plasmonic emitters (or antennas) at nanometer scales. Here, by using a control laser beam to induce a bubble (n=1.0) in water (n=1.333) to obtain a large index variation as high as |Δn|=0.333, the emission polarization of an ultra-small plasmonic emitter (~0.4λ 2 ) is experimentally switched at nanometer scales. The plasmonic emitter consists of two orthogonal subwavelength metallic nanogroove antennas on a metal surface, and the separation of the two antennas is only s x =120 nm. The emission polarization state of the plasmonic emitter is related to the phase difference between the emission light from the two antennas. Because of a large refractive index variation (|Δn|=0.333), the phase difference is greatly changed when a microbubble emerges in water under a low-intensity control laser. As a result, the emission polarization of the ultra-small plasmonic emitter is dynamically switched from an elliptical polarization state to a linear polarization state, and the change of the degree of linear polarization is as high as Δγ≈0.66.

“…[21] Apart from enhancing the decay-rates of emitters, plasmonic waveguides can also be utilized for engineering emission pattern and polarization of single photon emitters. [84] Furthermore, on-chip detection of plasmons and plasmon-plasmon quantum interference have also been demonstrated. [85][86][87] The main challenge in using plasmonic waveguides for quantum optical onchip circuits is propagation loss in the waveguides.…”

During the last two decades, many research groups have demonstrated coupling of single photon emitters to plasmonic waveguides, promising very high emission enhancements, for applications in quantum technologies. In this review, recent developments within this important research topic are discussed. Different plasmonic waveguide-quantum emitter configurations are compared from the application viewpoint by utilizing a figure-of-merit (FOM) reflecting the emission enhancement, coupling efficiency, and radiation loss. The experimental methods applied to obtain the coupled systems with high FOMs are described. Configurations that are exploited for reinforcing the coupling efficiency, i.e., the efficiency of funneling the emitted radiation into a plasmonic waveguide, are also considered as well as the scalability potential of various waveguide platforms. A recent experiment, in which enhanced light-matter interaction in a plasmonic waveguide is taken advantage of, resulting in the demonstration of non-linearity at the single emitter level, is discussed.

Basically, stand-alone QEs (i.e., in a homogeneous environment) exhibit several shortcomings that make their use in quantum systems and networks very problematic. The main QE challenging properties include their low spontaneous emission (SE) rates (due to limited transition dipole magnitudes), broad emission spectrum (due to phonon-mediated decoherence), and emission in practically all directions (due to its electric dipole nature). [6,7] In general, there are two different routes for shaping single-photon emission. One can conveniently make use of common optical components, including polarizers, waveplates, mirrors, and phase modulators, to change the polarization, direction, and wave front of single-photon emission. This classical (farfield) approach has been widely used for molding classical light, while being known for requiring bulky optical setups. Alternatively, one can use recently developed near-field coupling approaches that are based on utilizing either individual nanostructures or extended surface nanoarrays (metasurfaces). Placing QEs in a suitably nanostructured environment opens several avenues for single-photon generation
