“…In this work, we present a significant step towards realizing a complete semiconductorbased plasmonic switch referred to as a Surface Plasmon Polariton Diode (SPPD) [62][63][64][65]. Here, we build upon our past work [65], where we have demonstrated excitation and modulation of SPPs modes at the interface of the degenerately doped lattice-matched Indium Gallium Arsenide (In0.53Ga0.47As) PN ++ -junctions grown epitaxially on Indium Phosphide (InP) and proceed to the next important step by experimentally demonstrating the temporal response of the device. Small signal frequency response measurements are performed, clearly demonstrating frequency dependent optical modulation (switching) of SPP modes at the PN ++ junction.…”

“…This charge injection process results in modifying the P-layer's permittivity 𝜖 𝑝 . When applying external bias 𝑉 > 𝑉 𝑐 , where 𝑉 𝑐 is a critical voltage [65], some portion of the P-layer can acquire metal-like characteristics with 𝜖 𝑝 < 0, which results in hindering the propagation of the SPP modes within the active drift-diffusion region. This state of the device is considered as the 'OFF' state.…”

We present a transient response study of a semiconductor based plasmonic switch. The proposed device operates through active control and modulation of localized electron density waves, i.e., surface plasmon polaritons (SPPs) at degenerately doped In0.53Ga0.47As based PN++ junctions. A set of devices is designed and fabricated, and its optical and electronic behaviors are studied both experimentally and theoretically. Optical characterization shows far-field reflectivity modulation, a result of electrical tuning of the SPPs at the PN++ junctions for mid-IR wavelengths, with significant 3 dB bandwidths. Numerical studies using a self-consistent electro-optic multi-physics model are performed to uncover the temporal response of the devices’ electromagnetic and kinetic mechanisms facilitating the SPP switching at the PN++ junctions. Numerical simulations show strong synergy with the experimental results, validating the claim of potential optoelectronic switching with a 3 dB bandwidth as high as 2 GHz. Thus, this study confirms that the presented SPP diode architecture can be implemented for high-speed control of SPPs through electrical means, providing a pathway toward fast all-semiconductor plasmonic devices.

“…Based on these, they utilized the advantage of the selective light absorption and scattering of plasmonic metamaterial structures, local electric field constraints, and other properties to enhance light-matter interactions. It has been widely used in light modulator [36][37][38][39], light detector [40,41], photovoltaic solar energy [42,43], biological refractive index sensor [44,45], surface plasmon laser [46][47][48], photochemical catalysis [49,50], surface enhanced Raman spectroscopy [51,52], and optical holographic imaging [53,54]. With the development of theoretical research, plasmonic metamaterials have more overlaps with biology, chemistry, energy, electronics, materials, and other disciplines.…”

Ultraviolet (UV) electro-optic modulation system based on grapheneplasmonic metamaterials nanomechanical system (NEMS) with superlubricity is investigated. Due to the strong optical absorption intensity of graphene in the UV region and the combination of metamaterial structure based on surface plasmons, the modulation depth of the UV NEMS electro-optic modulator approaches as high as 8.5 times compared to the counterpart modulator in visible light region. Meanwhile, the superlubricity significantly reduces the power consumption of the UV electro-optic modulation system due to its extremely low friction coefficient. It also significantly improves the response speed of the modulator, which can reach the order of a nanosecond. The modulation voltage can be lower than 200 mV. The proposed electro-optic modulation system has a simple structure and high sensitivity, which is supposed to have important applications in UV optoelectronic devices and systems.

Nanophotonics considers the complex interactions between light and matter at the sub-wavelength scale. Recent progress in nanophotonics has revealed unprecedented optical phenomena, which have opened up the novel and rapidly developing fields of metamaterials, photonic crystals, and plasmonics. The last few decades have seen explosive growth in this field, from fundamental research to applications including condensed-matter physics, quantum photonics, near-field/far-field optics, biochemical sensing, deep learning for nanophotonic design, and nanofabrication/ nanomanufacturing. The International Conference on Metamaterials, Photonic Crystals, and Plasmonics (META) is an annual conference of researchers in metamaterials, nanophotonics, and other closely related topics. It covers a broad range of topics including, but not limited to, metasurfaces, meta-devices, topological effects in optics, two-dimensional materials, light-matter interaction in nano-cavities, plasmonic circuits, thermal engineering, and quantum photonic systems. The latest conference, META'19, was held in Lisbon, Portugal (July 23-26, 2019), where the latest trends and recent progress in nanophotonics were discussed to provide further insights for researchers. This special issue introduces a selection of cutting-edge original research and review papers from the conference. Metasurfaces can manipulate the optical properties of light with the ultrathin materials. Two groups review this topic in detail in this issue. Wei et al. [1] focus on the recent research progress in metasurfaces for holographic displays, polarization conversion, active modulation, and linear and nonlinear modulation; the authors discuss in detail the working principle and advantages of metasurfaces and provide many specific applications. Intaravanne and Chen [2] review the recent progress on metasurfaces, mainly focusing on metasurface devices for polarization detection and polarization profiles. The review also presents various applications of metasurface-based devices by manipulating arbitrary polarizations, with specific examples for high-resolution images, quick-response codes, color images, and holograms. Other topics on metasurfaces deal with the unique metasurface-driven optical properties, presented by three groups. Mun et al. [3] report a method to modulate the phase information of a Fano-resonant metasurface; they present an optical de-multiplexer that covers a broad wavelength range in the near-infrared region, and experimentally verify the extremely small full width at half-maximum. The proposed design approach can provide complete control of Fanoresonant metasurfaces for various applications including optical multiplexers, filters, and switches. Park et al. [4] present a metasurface deflector that can control the direction of emission of colloidal quantum dots; the design of metasurfaces was adapted from the optical Yagi-Uda nanoantenna, and the deflection efficiency of the device reaches up to 70%. The developed metasurface facilitates the integration of metasurfa...
