“…Coupling between the surface plasmons and the emitted light from LED by using a patterned aperture can be cause to enhancing the directivity of the emitted beam. The grating period has a great effect on the directivity and the far field emission of the patterned aperture can be written as (Dikken et al, 2016):…”

“…In recent years, the field of plasmonics has received considerable attention due to a wide variety of significant applications, including those that exploit surface plasmon polaritons (SPPs) 1–7 , optical metamaterials 8–12 and nanoantennas 13–16 . In optics, metals, such as gold (Au) and silver (Ag), are wildly utilized for building nanoarchitectures due to their potential for plasmonic resonance.…”

A highly efficient numerical approach for simulating the wideband optical response of nano-architectures comprised of Drude-Critical Points (DCP) media (e.g., gold and silver) is proposed and validated through comparing with commercial computational software. The kernel of this algorithm is the subdomain level discontinuous Galerkin time domain (DGTD) method, which can be viewed as a hybrid of the spectral-element time-domain method (SETD) and the finite-element time-domain (FETD) method. An hp-refinement technique is applied to decrease the Degrees-of-Freedom (DoFs) and computational requirements. The collocated E-J scheme facilitates solving the auxiliary equations by converting the inversions of matrices to simpler vector manipulations. A new hybrid time stepping approach, which couples the Runge-Kutta and Newmark methods, is proposed to solve the temporal auxiliary differential equations (ADEs) with a high degree of efficiency. The advantages of this new approach, in terms of computational resource overhead and accuracy, are validated through comparison with well-known commercial software for three diverse cases, which cover both near-field and far-field properties with plane wave and lumped port sources. The presented work provides the missing link between DCP dispersive models and FETD and/or SETD based algorithms. It is a competitive candidate for numerically studying the wideband plasmonic properties of DCP media.

“…Therefore, such SPP excitation schemes are not suitable for compact, portable and integrated SPP excitation. For more compact excitation of SPP, scattering of light by transmission through a metallic nano‐hole has been considered . Jing yang et al.…”

“…In all these cases, the nano‐hole SPP excitation schemes have the drawback of low excitation efficiency. In fact, when calculating the excitation efficiency of nano‐holes, the SPP power is normalized to the optical power in the nano‐hole and not the total input optical power . Therefore, SPP coupling efficiency numbers are even lower when the coupled SPP mode power is normalized to the total power in the input beam.…”

Fabrication method: Figure S1 shows the steps for fabricating the gabled Si tip SPP excitation device. To fabricate the sample, we first obtained a <100> Si wafer and grew 300 nm of SiO2 by thermal oxidation (18 mins in the Bruce technologies oxidation furnace at the Toronto Nano-fabrication Center-TNFC). Then we cleaved a small piece of sample from the oxidized Si wafer. As the next step, we made patterns of 500 nm wide lines and 200 m square pads of ma-N 2400 negative resist on top of the oxidized Si sample using Vistec E-beam lithography unit. Next, we etched the oxide layer using deep reactive ion etching using an Oxford Instruments PlasmaPro Estrelas100 DRIE System unit at the TNFC facilities. After that, we wet-etched the oxide masked Si sample in 45% KOH solution for 7 mins at 80 0 C temperature to create the gabled Si tip structures. The height of the gable tip after the wet etch was measured to be 6 m. Next, we deposited a thick (more than 6 m) PECVD oxide on top of the Sample containing the Si tip, using an Oxford Instruments PlasmaLab System 100 PECVD unit. Then we planarized the top surface of the deposited PECVD oxide using chemical mechanical polishing (CMP). The CMP of the top surface was carried out until the top oxide thickness was reduced to the approximate height of the tip of the Si chimney tip. Further CMP was not carried out to avoid destruction of the Si tip. We also polished the bottom surface of the sample (rough Si) for reducing the defused reflection while coupling light from the bottom. As the next step, we patterned negative resist (ma-N 2400) on the oxide surface for metal deposition and grating fabrication by lift off using the same electron beam lithographic system at TNFC. We used the 200 m square Si marker pads for alignment of the resist patterns for proper positioning of the grating. Then we deposited gold on top of the patterned resist using a Datacomp Electronics TES12D Thermal Evaporator and carried out lift off to fabricate the grating. In the sample layout, hence in the fabricated sample as well the 1 st grating was 10 microns away from the tip of the Si chimney. We fabricated several other gratings at varying distances from the Si tip to monitor the decay of the excited surface plasmon polariton as mentioned in the manuscript. Figure S2 shows the layout of the fabricated sample with the little opening for
