“…Therefore, the 2D PC is a better choice for designing optical devices due to many advantages such as nano size, complete PBG and better light manipulation to integrate in PIC. The 2D PC design with diverse components like LASER (Meier et al1999), filter (Fan et al1998), sensor (Fenzl et al2014), demultiplexer (Balaji et al 2016), logic gates (Zhang et al 2007), encoder (Mehdizadeh et al2017), Micro ring resonator (Ali Shahidinejad et al 2018), Add Drop filter (Joannopoulos et al1997;Hsiao et al2009;Mahmoud et al2012;Rajasekar et al2018;Sathyadevaki et al2017;Qiang, et al2004;Alipour-Banaei et al2014;Robinson et al2018;Rezaee et al2018;Rashki et a.2017;Chhipa et al2016, Alipour-Banaei et al2014Massoudi et al2019) and etc.…”

In this paper, two dimensional photonic crystal based Add Drop filter is designed for DWDM applications. The existing work concentrate in Coarse Wavelength Division Multiplexing (CWDM) and few filter design with DWDM with non-uniform channel spacing, and low quality factor. . The proposed Add Drop Filter (ADF) enhances the quality factor using Rounded Square Ring Resonator (RSRR) for ensuring efficient bandwidth in supporting WDM systems. The design consists of bus waveguide, drop waveguide and RSRR with inner quasi-square ring in the square lattice while dielectric constant of the Si rod is 11.68 which are hosted in the air. The line defect was created by removing 4 rods (Quasi ring) in the center of the inner square ring. The line defects in the cavity help to reduce the radiation field components surrounded by the resonator. The proposed design drops the unique wavelength 1636.2 nm from a spectrum. The performance parameters of ADF are investigated using 2DFinite Difference Time Domain (FDTD) algorithm. The proposed ADF drops the narrow bandwidth of 0.7 nm, high quality factor of 2337, dropping efficiency (ON State) of 100 %, which is highly sufficient to support WDM systems for future Photonic Integrated Circuits (PIC). Further, the impact of functional parameters such as transmission efficiency, quality factor, bandwidth are investigated by varying the structural parameters, namely, adjacent rod radius, scatterer rod radius, coupling rod radius, lattice constant, inner rod radius and rod radius. The size of the device is 412.76 µm 2 .

“…In last decades it has been shown that photonic crystals (PhCs) [1,2] which consist of regular arrangement of dielectric materials with periodic refractive indices can be very useful for designing different kinds of optical devices [3][4][5]. The realization of optical filters [6][7][8][9][10], demultiplexers [11][12][13][14][15][16], logic gates [17][18][19][20][21][22], coders [23][24][25][26][27][28][29], adders [30][31][32][33][34][35] and analog to digital converters [36][37][38][39][40] proves the ability of photonic crystals for playing a crucial role in the next generation of all optical networks. An all optical phase shift keying (PSK) demodulator was designed using 2D PhCs [41].…”

In this paper we will propose and design an all optical amplitude shift keying demodulator using a photonic crystal based nonlinear ring resonator. The proposed structure will be designed such that it can generate digital 0 and 1 based on the amplitude of the input signal. The working mechanism is based on controlling the optical behavior of the resonant ring using optical intensity. The proposed structure was simulated using plane wave expansion and finite difference time domain methods. The simulation results show that the rise and fall times for the proposed structure are 0.5 and 0.1 ps, respectively.

“…The design is reported with higher transmission efficiency up to 90% [35]. Following that, a 12-channel DWDM demultiplexer was designed using central defect (Rm) with a high Q-factor of 7890, transmission efficiency, uniform spectral linewidth, and uniform channel spacing of about 0.2 nm, −42 dB [36]. From the literature survey, it has been studied that optical demultiplexers are designed using different shapes and resonant cavities with different lattices, and are reported to have high transmission efficiency, Q-factor and minimal crosstalk.…”

We propose a new integrated demultiplexer model using the two-dimensional photonic crystal (2D PC) through the hexagonal resonant cavity (HRC) for the International Telecommunication Union (ITU) standard. The integrated model of demultiplexer for both 25 GHz and 50 GHz has been designed for the first time. The demultiplexer consists of bus input waveguide, drop waveguide, Hexagonal Resonant Cavity (HRC), 6 Air Hole Filter (6-AHF), 7 Air Hole Filter (7-AHF). The 7-AHF is used to filter 25GHz wavelength, and the 6-AHF filter is used to filter 50 GHz wavelength. The Q-factor on the designed demultiplexer is flexible based on the idea of increasing the number of air holes between drop waveguide and resonant cavity. The demultiplexer is designed to drop maximum 8 resonant wavelengths. One side of demultiplexer is able to drop 50 GHz ITU standard wavelengths, which are of 1556.3 nm, 1556.7 nm, 1557.1 nm and 1557.5 nm, and further the other facet is able to drop 25 GHz wavelengths, which are of 1551.4 nm, 1551.6 nm, 1551.8 nm, and 1552.0 nm. The proposed demultiplexer may be carried out within the integrated dual system. This system is able to lessen the architecture cost and the size is miniaturized substantially.
