“…SiO 2 [8,22], respectively, and the relative permittivities of the Si and Ag layers are extracted from data from Palik, and Johnson and Christy, respectively [23,24]. It is essential to mention that unlike some previously proposed PNAs, which have used gold as a metal [18,25,26], silver is a good candidate for plasmonic devices due to its superior characteristics, such as the smallest total damping rate (Γ=0.02 eV), lowest loss, much better SPP confinement at telecommunication wavelengths, highest SPP quality factor…”

“…Additionally, until now, the performance of most PNAs is based on the plasmonic resonance principle [14,17], but recently, some proposed nano-antennas have been suggested based on coupled hybrid plasmonic waveguides (CHPWs) [8,10,[18][19][20][21][22][23][24][25][26]. In this case, because of using the CHPW, not only is the impedance matching well done, but also these hybrid PNAs are able to receive the optical signal through the CHPW feed or direct it to the free space from the radiation element of the PNAs efficiently in a wide frequency range [8,10,18].…”

In this paper, a wideband hybrid plasmonic V-shaped nano-antenna is proposed based on coupled hybrid plasmonic waveguide (CHPW) feeding to increase the surface plasmon propagation length. The CHPW specifications are investigated analytically and numerically to obtain the dispersion relation and propagation length using the genetic algorithm and the finite element method, respectively. Moreover, the proposed V-shaped nano-antenna, with a fractional bandwidth of ∼86% and a maximum efficiency of 98%, is able to receive/transmit optical signals at three telecommunication wavelengths of 850, 1310, and 1550 nm with high realized gains of 10.5, 9.39, and 9.05 dB, respectively. The shape of the radiation pattern, with a main lobe along the antenna axis, makes this antenna appropriate for point-to-point connections in inter-or intra-chip optical wireless links and networks, which is studied comprehensively in this article. Furthermore, to obtain a high optical power signal and tune the antenna orientation, the performance of the antenna is investigated with two different types of array structure, single row and square, and its applications for energy harvesting and beam steering are studied. The fabrication feasibility of the nano-antenna is realizable based on complementary metal-oxide-semiconductor technology.

“…SPP waveguides based on metal nanostructures were regarded as one of the most effective platform for subwavelength waveguiding and great progress has been achieved in the past decades. Particularly, the recently developed hybrid plasmonic waveguides have been considered as one of the most attractive options because of the possibility to achieve low-loss subwavelength waveguiding [42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78]. Among various hybrid plasmonic waveguides, an SOI-compatible hybrid nanoplasmonic waveguide, proposed for the first time by Dai et al [12], is one of the most attractive designs as silicon photonics is CMOS (complementary metal oxide semiconductor) compatible and has become very popular for realizing PICs.…”

Plasmonic nanostructures have attracted intensive attention for many applications in recent years because of the field enhancement at the metal/dielectric interface. First, this strong field enhancement makes it possible to break the diffraction limit and enable subwavelength optical waveguiding, which is desired for nanophotonic integrated circuits with ultra-high integration density. Second, the field enhancement in plasmonic nanostructures occurs only for the polarization mode whose electric field is perpendicular to the metal/dielectric interface, and thus the strong birefringence is beneficial for realizing ultra-small polarization-sensitive/selective devices, including polarization beam splitters, and polarizers. Third, plasmonic nanostructures provide an excellent platform of merging electronics and photonics for some applications, e.g., thermal tuning, photo-thermal detection, etc. Finally, the field enhancement at the metal/dielectric interface helps a lot to realize optical sensors with high sensitivity when introducing plasmonic nanostrutures. In this paper, we give a review for recent progresses on the utilization of field enhancement in plasmonic nanostructures for these applications, e.g., waveguiding, polarization handling, heating, as well as optical sensing.
