“…Table 1 demonstrates that this parameter is obtained as large as 0.42 for the proposed device. The calculated value for the mentioned ratio is more than obtained ratio in Ref [29] (0.35) and is suitable for light coupling from output ports to other devices. With regard to the obtained results, the presented structure can be proposed for using in optical integrated circuits.…”

“…PCs are structures composed of periodic layers with different dielectric constants and demonstrate useful characteristics such as photonic band gap (PBG) [3], slow light regime [5][6][7], and self-collimation [8][9][10][11]. Because of their compact size and the aforementioned properties, they are promising candidates in realizing all-optical devices such as optical waveguides [10][11][12], filters [13][14][15][16][17][18], demultiplexers [19][20][21][22][23][24][25], switches [26][27][28][29][30], logic gates [31][32][33][34][35][36], encoders [37][38][39][40][41][42], decoders [43][44][45][46][47][48], and analog-to-digital converters …”

All-Optical Ultra-Fast Graphene-Photonic Crystal Switch

et al. 2019

In this paper, an all-optical photonic crystal-based switch containing a graphene resonant ring has been presented. The structure has been composed of 15 × 15 silicon rods for a fundamental lattice. Then, a resonant ring including 9 thick silicon rods and 24 graphene-SiO2 rods was placed between two waveguides. The thick rods with a radius of 0.41a in the form of a 3 × 3 lattice were placed at the center of the ring. Graphene-SiO2 rods with a radius of 0.2a were assumed around the thick rods. These rods were made of the graphene monolayers which were separated by SiO2 disks. The size of the structure was about 70 µm2 that was more compact than other works. Furthermore, the rise and fall times were obtained by 0.3 ps and 0.4 ps, respectively, which were less than other reports. Besides, the amount of the contrast ratio (the difference between the margin values for logics 1 and 0) for the proposed structure was calculated by about 82%. The correct switching operation, compactness, and ultra-fast response, as well as the high contrast ratio, make the presented switch for optical integrated circuits.
