We demonstrate inverse design of plasmonic nanoantennas for directional light scattering. Our method is based on a combination of full-field electrodynamical simulations via the Green dyadic method and evolutionary optimization (EO). Without any initial bias, we find that the geometries reproducibly found by EO, work on the same principles as radio-frequency antennas. We demonstrate the versatility of our approach by designing various directional optical antennas for different scattering problems. EO based nanoantenna design has tremendous potential for a multitude of applications like nano-scale information routing and processing or single-molecule spectroscopy. Furthermore, EO can help to derive general design rules and to identify inherent physical limitations for photonic nanoparticles and metasurfaces.

Our approach unifies the emerging modular nanophotonic-circuit paradigm 32 with hybrid-integration of plasmonic nano-elements on industrystandard waveguides 27,26 , extending the range of accessible structures to efficient hybrid plasmonic waveguides culminating in deep-subwavelength mode volumes, by performing three difficultto-access optical functions (namely rotation, nano-focusing, and nonlinear conversion) back-to-back and on an integrated platform.

“…PICs and plasmonics can be married using hybrid plasmonic waveguides (HPWGs) containing a low-index buffer layer between the metal and the high-index waveguide, enabling relatively low propagation loss without sacrificing plasmonic confinement, and providing a convenient intermediate interface for coupling between photonic and plasmonic waveguides 19,20 . Whereas the efficient energy transfer between PIC-compatbile photonic and plasmonic structures has been under intense experimental investigation with a diverse range of functionalities [21][22][23][24][25][26][27] , including HPWG experiments demonstrating tight confinement and low propagation losses [28][29][30] , nonlinear experiments using this platform have been limited 31 .…”

Photonic integrated circuits (PICs) are revolutionizing nanotechnology, with far-reaching applications in telecommunications, molecular sensing, and quantum information. PIC designs rely on mature nanofabrication processes and readily available and optimised photonic components (gratings, splitters, couplers). Hybrid plasmonic elements can enhance PIC functionality (e.g., wavelength-scale polarization rotation, nanoscale optical volumes, and enhanced nonlinearities), but most PIC-compatible designs use single plasmonic elements, with more complex circuits typically requiring ab initio designs. Here we demonstrate a modular approach to post-processes off-the-shelf silicon-on-insulator (SOI) waveguides into hybrid plasmonic integrated circuits. These consist of a plasmonic rotator and a nanofocusser, which generate the second harmonic frequency of the incoming light. We characterize each component's performance on the SOI waveguide, experimentally demonstrating intensity enhancements of more than 200 in an inferred mode area of 100 nm 2 , at a pump wavelength of 1320 nm. This modular approach to plasmonic circuitry makes the applications of this technology more practical.

“…Polarization‐sensitive plasmonic devices, which show large controllability with high contrast, are successfully demonstrated, directional launching and switching of SPPs, multiplexed plasmonic lenses, polarization‐controlled resonators, SPP beam steering, and caustic beam generation, for instances. Other reports of polarization generators and converters, optical routers, and multiplexed holography show strong potential for wide variety of applications. Consider a columnar array of rectangular nano‐apertures that are arranged along the y ‐axis with a subwavelength period, as depicted in Figure a.…”

Polarization is one of the fundamental properties of light, which is inherited from the vectorial nature of electromagnetic waves. Measuring states of polarizations (SOPs) is widely used for remote sensing applications. A number of ultracompact polarimeters that analyze SOPs at a single detection without splitting of incident beams have been demonstrated recently. However, the development of a broadband polarimeter remains challenging due to the resonant feature of their building blocks. Here, an ultracompact polarimeter that retrieves the SOP of incident light with broad operation bandwidth at near-infrared wavelengths is proposed. Surface plasmon polaritons (SPPs) excited by X-shaped aperture arrays are utilized as intensity probes. Full-Stokes parameters are retrieved by detecting the SPP intensities. The proposed polarimeter is demonstrated experimentally and can measure SOPs at wavelengths from 750 nm to 1050 nm. This work can help to develop more compact polarization-sensitive optical systems, such as polarimetry, ellipsometry, and optical routers.
