“…Figure 10 b shows the relationship between the ER and the wavelength. Generally speaking, an ER larger than 20 dB can be considered an indication of successful splitting [ 31 ]. The bandwidth of a PBS is defined as the wavelength range in which the ER is larger than 20 dB.…”

In this work, a polarization beam splitter (PBS) based on surface plasmonic resonance is proposed and realized in a designed photonic crystal fiber (PCF). The PCF consists of two kinds of air holes with different diameters. Two solid silica cores near the center of the PCF are established by removing the cladding air holes. A gold film is plated at the external surface of the central air hole of the PCF to excite the surface plasmonic resonance. In order to minimize the length and improve the operation bandwidth of the PBS, the influences of the transversal structural parameters of the PCF are investigated in the context of both X and Y polarization beams. It was found that a 123.6-μm-long PBS with an operation bandwidth of 314 nm could be realized after the global optimization of five structural parameters. The proposed PBS may have potential applications in micro-/nano-optical systems for sensing and communications.

“…A recent approach developed an Mach-Zehnder interferometer (MZI) all-plasmonic 116 Gbps electro-optical modulator from a single layer of gold using a substrate-independent process [149]. High-compactness, high-speed, and low-cost were reached through exploitation of the electro-optical Pockels effect [150,151] and the integration with a multicore optical fiber for SPR excitation [152] and polarization beam splitters [153][154][155][156]. An electro-optical modulator, based on a ring-resonator coupled to a buried low-loss silicon photonic waveguide, has also been recently proposed [157].…”

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.

“…Therefore, some investigations are mainly focused on the DC-PCF PBS. In 2019, Zhao et al designed a hexagonal lattice DC-PCF PBS with two elliptical air holes and two gold-coated air holes based on the surface plasmon resonance (SPR) effect, whose splitting length (SL) is 104 μm and splitter bandwidth (SB) covers the S + C + L + U band [21]. In 2020, Chen et al reported a short PBS based on the DC-PCF with As2S3 layer, whose SL is 1.0 mm, SB is 280 nm, and insertion loss (IL) of X-polarized light is as low as 0.18 dB [22].…”

In this paper, a simple structure dual-core photonic crystal fiber (SS-DC-PCF) polarization beam splitter (PBS) based on the surface plasmon resonance (SPR) effect and symmetric dual-core coupling mode theory is proposed. For the proposed SS-DC-PCF-1 PBS, the coupling lengths (CLs) and coupling length ratio (CLR) are analyzed, and the variations of the normalized output powers with the propagation length are investigated for the chosen wavelengths 1.434, 1.451, and 1.469 µm. The extinction ratio in cores A and B are compared at the three splitting lengths (SLs) 170, 173, and 176 µm. When the optimal SL is 176 µm, the splitting bandwidth (SB) is 255 nm (1.437–1.692 µm), and the insertion loss (IL) is less than 0.043 dB. The regulations of the CLs and CLR with the change of the structure parameters are analyzed. For the proposed SS-DC-PCF-2 PBS, the optimal SL is 232 µm, the SB is 201 nm (1.249–1.450 µm), and the IL is less than 0.042 dB. Finally, it is demonstrated that the total SB of the proposed SS-DC-PCF-1 PBS and SS-DC-PCF-2 PBS is 443 nm (1.249–1.692 µm), which can cover the O + E + S + C + L + U band, even if the gold film thickness changes by ± 1 n m . The proposed SS-DC-PCF PBS has excellent performances, such as ultrashort SL, ultrawide SB, ultralow IL, and good error-tolerance rate. It will have important applications in all-fiber optical systems.
