In this paper, a high sensitivity, polarization preserving photonic crystal fiber (PCF), based on circular air holes for sensing in the terahertz (THz) band, is presented. The finite element method, a practical and precise computational technique for describing the interactions between light and matter, is used to compute the modal properties of the designed fiber. For the designed PCF, comprising of circular air holes in both the cladding and in the porous core, a relative sensitivity of 73.5% and a high birefringence of 0.013 are achieved at 1.6 THz. The all circular air-hole structure, owing to its simplicity and compatibility with the current fiber draw technique for PCF fabrication, can be realized practically. It is anticipated that the designed fiber can be employed in applications such as detection of biological samples and toxic chemicals, imaging, and spectroscopy.

“…POF has several advantages such as robustness to mechanical stress and electromagnetic interference, easy installation, low cost connectors and low-price systems. Another variation of the POF is the multicore POF (MC-POF) that consists from many cores surrounded in a sea of cladding, those fibers have much resemblance to the multicore photonic crystal fibers [2][3]. MC-POF utilize the photonic bandgap alongside to the modified total internal reflection mechanisms allowing design of new compact optical components [4].…”

Wavelength division multiplexing (WDM) is a good solution for increasing data bitrate communication of multicore polymer optical fiber (MC-POF) based visible light communication (VLC) system. However, this solution requires adding more optical components to the system which can limit its performance. In order to solve this issue, we propose a new design for an RGB demultiplexer based on polycarbonate (PC) MC-POF structure. The new structure is based on replacing several air-holes areas with PC layers over the fiber length which enables controlling the light propagation direction between the pc layers. The positions of the PC layers and the key geometrical parameters of the MC-POF were optimized and analyzed utilizing the beam propagation method (BPM). Results show that an RGB wavelength splitter can be obtained over a light propagation of 20 mm with an excellent crosstalk of-19.436 to-26.474 dB, low losses of 0.901 to 1.246 dB and a large bandwidth of 5.6 to 11.3 nm.

“…[5,6]. Multicore PCFs are also finding some special applications due to their optical waveguide and photonic design possibilities, such as the development of optical splitters with larger splitting ratios and optical couplers with lower coupling lengths [7,8]. Diode-pumped alkali lasers (DPALs) are another special field of application, where embedding the alkali gas in hollow-core PCFs was shown to be an effective method of overcoming high-power limitations [9].…”

This paper proposes a hexagonal photonic crystal fiber (H-PCF) structure with all circular air holes in order to simultaneously achieve ultrahigh birefringence and high nonlinearity. The H-PCF design consists of an asymmetric core region, where one air hole is a reduced diameter and the air hole in its opposite vertex is omitted. The light-guiding properties of the proposed H-PCF structure were studied using the full-vector finite element method (FEM) with a circular perfectly matched layer (PML). The simulation results showed that the proposed H-PCF exhibits an ultrahigh birefringence of 3.87 × 10−2, a negative dispersion coefficient of −753.2 ps/(nm km), and a nonlinear coefficient of 96.51 W−1 km−1 at an excitation wavelength of 1550 nm. The major advantage of our H-PCF design is that it provides these desirable modal properties without using any non-circular air holes in the core and cladding region, thus making the fiber fabrication process much easier. The ultrahigh birefringence, large negative dispersion, and high nonlinearity of our designed H-PCF make it a very suitable candidate for optical backpropagation applications, which is a scheme for the simultaneous dispersion and nonlinearity compensation of optical-fiber transmission links.
