Ultra-broadband, efficient and unidirectional surface plasmon polariton (SPP) launching is of great concern in plasmonic devices and circuits. To address this challenge, a novel method adopting deep-subwavelength slits of subwavelength period (λSPP/4 ~ λSPP/3) in a thick metal film and under backside illumination is proposed. A new band pattern featuring broadband and wide angular characteristics, which is due to the coupling of the zeroth-order SPP resonance at the superstrate–metal interface and the first-order SPP resonance at the metal–substrate interface, is observed for the first time in the dispersion diagram. Unidirectional SPP launching efficiency of ~50%, ultra-broad bandwidth of up to 780 nm, covering the entire optical fiber communication bands, and relatively wide angular range of 7° are achieved. This remarkable efficient, ultra-broadband and wide angular performance is demonstrated by carefully designed experiments in the near infrared regime, showing good agreement with numerical results.

“…The SPP fields calculated with the analytical equation (4) agree well with that of the FDTD simulation as long as the field position is larger than 100 nm. Zhang's group [24,[26][27][28][29][30] has shown that the SPP fields launched from an arbitrary slit on a 2D metal surface, such as a SPP Fresnel zone plate [24] illustrated in Figure 2c, can be calculated by applying the Huygens-Fresnel principle. Every point of the slit can be considered as a secondary SPP point source with fields described by equation (4).…”

“…One plasmonic demultiplexer, which consists of concentric grooves with periodic projections on a line, allows for sorting light with different wavelengths into different plasmonic guiding channels [29]. The concentric grooves guarantee that all the launched SPPs from these grooves are well focused and the periodic projections of these grooves enable effective dispersion of the SPPs with respect to their wavelengths.…”

-Plasmonics, which allows for manipulation of light field beyond the fundamental diffraction limit, has recently attracted tremendous research efforts. The propagating surface plasmon polaritons (SPPs) confined on a metal-dielectric interface provide an ideal two-dimensional (2D) platform to develop subwavelength optical circuits for on-chip information processing and communication. The surface plasmon resonance of rationally designed metallic nanostructures, on the other hand, enables pronounced phase and polarization modulation for light beams travelling in three-dimensional (3D) free space. Flexible 2D and free-space propagating light manipulation can be achieved by encoding plasmonic nanostructures on a 2D surface, promising the design, fabrication and integration of the nextgeneration optical architectures with substantially reduced footprint. It is envisioned that the encoded plasmonic nanostructures can significantly expand available toolboxes for novel light manipulation. In this review, we presents the fundamentals, recent developments and future perspectives in this emerging field, aiming to open up new avenues to developing revolutionary photonic devices.
