“…Besides, the device designed in [23,25] employed elliptical and square shaped rods that are difficult to design and fabricate. Hence, the designed all-optical compact two-port splitter has very desirable line width, spacing between the channels, transmission efficiency, and quality factor compared to the devices proposed in the literature [23][24][25][26][33][34][35]. Thus, the designed device is well suited for photonic integrated circuit applications.…”

An all-optical compact polarization T splitter based on 2-dimensional photonic crystal with uniform structural and bandgap characteristics is proposed in this paper. A square lattice of silicon substrate with embedded air holes is used to create the proposed structure. Linear waveguides with 90 • bends are created for light propagation by removing a number of holes to build the structure. Plane Wave Expansion (PWE) and Finite Difference Time Domain (FDTD) methods are employed for simulating the structure. The transmittance of transverse electric (TE) polarized mode at 1550 nm is 96%. The structural parameters, such as air hole radius and dielectric constant, are homogeneous throughout the structure, making production easier and reducing fabrication errors. The proposed polarization splitter has a simple design with small footprints and high Q factor to meet the demands of current optical integrated circuits.

“…Several studies have been conducted to develop many of these devices [2][3], including demultiplexers [4], sensors [5], logic gates [6], and beam splitters [7] for photonic integrated circuits (PIC) and telecommunication applications. Most of these devices are designed using 2D-PhC as a slab, enabling the integration of silicon-on-insulator (SOI) technology.…”

In this study, a new design of 1  2 photonic crystal beam splitters is proposed to achieve symmetrically higher power splitting. Two different splitters based on hybrid couplers made from silicon (Si) and poly(methyl methacrylate) (PMMA) materials were studied. One splitter had two outputs, and the other had four outputs. The PMMA temperature was varied from 0 °C to 130 °C to enhance the optical performance of the proposed splitters. The power intensity and photonic band gap (PBG) values were numerically investigated using the finite-difference time-domain (FDTD) and plane wave expansion (PWE) methods. The effect of temperature on these values was also studied to obtain the optimal conditions for high efficiency. The efficiency values were satisfactory. They could reach 49.9 % from the two output ports at a temperature of 80 °C.
