“…PhCs with photonic band gaps (PBGs) also have been used to design multiple devices for photovoltaic applications [ 13 ] like filters [ 14 ], routers [ 15 ], resonators [ 16 ], optical logic gates [ 17 ], adders [ 18 ], phase shifters [ 19 ] and some all-optical memory components [ 20 , 21 , 22 , 23 , 24 , 25 , 26 ]. The PBGs of some different types of PhCs are generally calculated by the plane wave expansion method (PWEM) based on the Bandsolve module in Rsoftwave, which is a mathematical method used to expand a wave function or physical quantity into a linear combination of plane waves.…”

A novel terahertz polarization isolator using a two-dimensional square lattice tellurium rod array is numerically investigated at the interesting band of 0.22 THz in this short paper. The isolator is designed by inserting six hexagonal tellurium rods into a fully polarized photonic crystals waveguide with high efficiency of −0.34 dB. The TE and TM photonic band gaps of the 7 × 16 tellurium photonic crystals are computed based on the plane wave expansion method, which happen to coincide at the normalized frequency domain from 0.3859(a/λ) to 0.4033(a/λ), corresponding to the frequency domain from 0.2152 to 0.2249 THz. The operating bandwidth of the tellurium photonic crystals waveguide covers 0.2146 to 0.2247 THz, calculated by the finite element method. The six hexagonal tellurium rods with smaller circumradii of 0.16a serve to isolate transverse electric waves and turn a blind eye to transverse magnetic waves. The polarization isolation function and external characteristic curves of the envisaged structure are numerically simulated, which achieves the highest isolation of −33.49 dB at the central frequency of 0.2104 THz and the maximum reflection efficiency of 98.95 percent at the frequency of 0.2141 THz. The designed isolator with a unique function and high performance provides a promising approach for implementing fully polarized THz devices for future 6G communication systems.

“…Since the photonic crystal (PhC) was first investigated [ 4 , 5 ], microwave photonic devices based on PhCs for high-frequency operations have drawn considerable concern and attracted much research [ 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. PhCs have been shown to be an effective medium for transmitting as well as controlling electromagnetic waves, which can readily facilitate the miniaturization and integration of devices at the same time [ 13 , 14 , 15 , 16 , 17 , 18 ].…”

Broadband 5G communication requires the operation of nonreciprocal devices in the Ku band. A wideband photonic crystal circulator is implemented by introducing two partial-height triangular Ni-Zn ferrites into the Al2O3 ceramic rod-arrays. The asymmetric sizes of the two equilateral triangles paired with self-matching effectively extend the bandwidth of the circulator eight times over that of the symmetric scheme. Numerical simulations demonstrate that the photonic crystal circulator can obtain a bandwidth of 1.00 GHz with an isolation 25.75 dB and an insertion loss 0.381 dB through optimized matched triangle size ratio, suitable for applications in future communication systems.
