“…In addition to the typical cases mentioned above, many specialist studies are currently making use of the plasmonic tweezer platform. For instance, Golmohammadi et al proposed a jagged plasmonic waveguide-generated trapping system to operate as a narrow band filter for polychromatic light by fixing core-shell particles within a fluidic medium 363 . They also demonstrated the function of this system in an optical telecommunication window based on plasmonic forces acting on the particles.…”

Optical tweezers and associated manipulation tools in the far field have had a major impact on scientific and engineering research by offering precise manipulation of small objects. More recently, the possibility of performing manipulation with surface plasmons has opened opportunities not feasible with conventional far-field optical methods. The use of surface plasmon techniques enables excitation of hotspots much smaller than the free-space wavelength; with this confinement, the plasmonic field facilitates trapping of various nanostructures and materials with higher precision. The successful manipulation of small particles has fostered numerous and expanding applications. In this paper, we review the principles of and developments in plasmonic tweezers techniques, including both nanostructure-assisted platforms and structureless systems. Construction methods and evaluation criteria of the techniques are presented, aiming to provide a guide for the design and optimization of the systems. The most common novel applications of plasmonic tweezers, namely, sorting and transport, sensing and imaging, and especially those in a biological context, are critically discussed. Finally, we consider the future of the development and new potential applications of this technique and discuss prospects for its impact on science.

“…Analogous to the prism coupler approach, these plasmonic grating structures have also been used for sensing and biosensing applications [41][42][43][44]. In telecommunications, their applications range from transmission lines to optical modulators [45][46][47][48][49][50]. In contrast to SPR approaches, LSPRs are excited by freely propagating light impinging on metallic nanoparticles or other finite structures.…”

Plasmonic materials, when properly illuminated with visible or near-infrared wavelengths, exhibit unique and interesting features that can be exploited for tailoring and tuning the light radiation and propagation properties at nanoscale dimensions. A variety of plasmonic heterostructures have been demonstrated for optical-signal filtering, transmission, detection, transportation, and modulation. In this review, state-of-the-art plasmonic structures used for telecommunications applications are summarized. In doing so, we discuss their distinctive roles on multiple approaches including beam steering, guiding, filtering, modulation, switching, and detection, which are all of prime importance for the development of the sixth generation (6G) cellular networks.

“…This leads to LDOS enhancement of quantum emitters in the coupled emitter-antenna systems. In this direction, metallic antennas enable one to modify the SE rate of quantum emitters due to the high near-field enhancement attained by localized surface plasmon resonances (LSPRs) [26][27][28][29][30]. Metallic nanorods [31] and ring resonators [32] are highly effective plasmonic sub-wavelength antennas for enhancing the SE rate of quantum emitters through the excitation of LSPRs, including transversal and longitudinal plasmonic modes in nanorods, and concurrent electric and magnetic resonant modes in ring resonators.…”

We exploit InSb’s magnetic-induced optical properties to design THz sub-wavelength antennas that actively tune the radiative decay rates of dipole emitters at their proximity. The proposed designs include a spherical InSb antenna and a cylindrical Si-InSb hybrid antenna that demonstrate distinct behaviors. The former dramatically enhances both radiative and non-radiative decay rates in the epsilon-near-zero region due to the dominant contribution of the Zeeman splitting electric octupole mode. The latter realizes significant radiative decay rate enhancement via magnetic octupole mode, mitigating the quenching process and accelerating the photon production rate. A deep learning-based optimization of emitter positioning further enhances the quantum efficiency of the proposed hybrid system. These novel mechanisms are promising for tunable THz single-photon sources in integrated quantum networks.
