“…The design includes topology optimization with a Y junction structure in the hexagonal lattice of air holes to obtain maximum power efficiency. The authors in (Li et al 2019) have designed a polarization-independent 1 x 3 optical splitter by using the concept of the self-collimation effect. Although the design has a transmission efficiency of 95% in Transverse Electric (TE) mode, the resonant wavelength is limited to 1310 nm.…”

In this paper, a compact six-channel optical demultiplexer and coupler have been designed using a novel photonic crystal resonator for Intermediate Frequency Over Fiber (IFoF) in Fifth Generation (5G) networks. The demultiplexer and coupler differ from the existing work with the introduction of defected pentagon and trapezium structured resonator and its positioning in the IFoF enabled 5G heterogeneous fiber wireless network. Point defects and displacement of photonic crystal rods have been introduced in these resonators and the structure of the waveguide is altered to exhibit the demultiplexer and coupler design. The proposed demultiplexer operates in S and C band and the coupler functions in C and L band. The footprint of the demultiplexer and coupler is found to be 270 µm 2 . The minimum and maximum quality factor of the demultiplexer is found to be 1823 and 3422, respectively. The maximum and minimum cross-talk of the demultiplexer using pentagon resonator is found to be −10 and −34 dB, respectively.

In this paper, a photonic crystal structure based on nonlinear cavities has been proposed to improve the time response of a 2-to-4 decoder. The structure includes an array of chalcogenide rods with an air gap in which the spatial period of rods is 500 nm. The radius of the fundamental rods is assumed to be 125 nm, which results in a photonic bandgap of 1092–1724 nm at TM mode. Three cavities, including the nonlinear rods with a Kerr coefficient of 10 − 14 m 2 / W , drop the incoming waves concerning the amount of optical intensity. The finite-difference time-domain method was used to calculate the components of the electric and magnetic fields throughout the structure. The time analysis of the device shows the rise time is equal to 200 fs, which is less than one for the previous structures. The area of 110 µ m 2 and the margins of 4% and 88% for logics 0 and 1 are other advantages of the proposed structure. Based on the obtained results, it was proven that the performance of the 2-to-4 photonic crystal-based decoder has been improved by this work.
