“…Compared with the known splitters of the same type, this splitter has better spectral efficiency. In addition, compared with the literature, [22] the operating bandwidth of this splitter is 78 nm wider. In short, it has great application prospects in future ultra-wideband, integrated and high-speed all-optical network systems.…”

A novel ultra-broadband polarization splitter based on dual-core photonic crystal fiber (DC-PCF) is designed. The full-vector finite element method (FEM) and coupled-mode theory are employed to investigate the characteristics of the polarization splitter. According to the numerical results, graphene-filled layer can not only broaden the working bandwidth but also reduce the size of polarization splitter. Furthermore, the fluorine-doped region and the germanium-doped region could broaden the bandwidth. Apart from that, the 4.78-mm-long polarization splitter can achieve an extinction ratio of -98.6 dB at the wavelength of 1550 nm. When extinction ratio is less than -20 dB, the range of the wavelength is 1027-1723 nm with a bandwidth of 696 nm. Overall, the polarization splitter can be applied to all-optical network communication system in the infrared and near-infrared wavelength range.

“…According to the working principle, when the mixed polarized light enters the core A or core B, it will be completely split into the X-pol light and Y -pol light at a specific splitting length. [31] In the following, the normalized output power (NOP) is used to describe the transfer of the light energy between the core A and the core B at different propagation distances: [32] P X,Y out,A = P in cos 2 π 2…”

In this paper, a novel polarization beam splitter (PBS) based on dual-core photonic crystal fiber (DC-PCF) is proposed. The proposed DC-PCF PBS contains two kinds of lattices and three kinds of air holes to form the asymmetrical elliptic dual-core structure. By using the full-vector finite element method, the propagation characteristics of the proposed DC-PCF PBS are investigated. The simulation results show that the bandwidth of the proposed DC-PCF PBS can be up to 340 nm, which covers the S + C + L + U communication bands, the shortest splitting length is 1.97 mm, and the maximum extinction ratio appears near wavelength 1550 nm. Moreover, the insertion loss of the proposed DC-PCF PBS is very low. It is believed that the proposed DC-PCF PBS has important applications in the field of all-optical communication and network.

“…Here, we present an on-fiber ultrashort PBS based on a dual-core PCF design to demonstrate the multiple strengths of our 3D printing approach. Several sub-mm dual-core PCF PBS designs have been proposed over recent years [27][28][29][30]); however, the limitations of current PCF fabrication methods have prevented their successful manufacture. Indeed, the dual-core geometries that have been proposed in the literature to date have all been generally asymmetric, with the inclusion of holes of different sizes and shapes, all factors that add significant complexity to the design of the preform.…”

Optical waveguide segments based on geometrically unbound photonic crystal fiber (PCF) designs could be exploited as building blocks to realize miniaturized complex devices that implement advanced photonic operations. Here, we show how to fabricate optical waveguide segments with PCF designs by direct high-resolution 3D printing and how the combination of these segments can realize complex photonic devices. We demonstrate the unprecedented precision and flexibility of our method by fabricating the first-ever fiber polarizing beam splitter based on PCFs. The device was directly printed in one step on the end-face of a standard single-mode fiber and was 210 µm long, offering broadband operation in the optical telecommunications C-band. Our approach harnesses the potential of high-resolution 3D printing and of PCF designs paving the way for the development of novel miniaturized complex photonic systems, which will positively impact and advance optical telecommunications, sensor technology, and biomedical devices.
