“…Despite having different functionalities, all these devices have in common that they are designed based on an optical resonator. Different shapes of PCRR have been proposed, such as circular [45][46][47][48][49][50][51][52][53][54][55][56][57], T-shaped [46][47][48]59], elliptical [49], octagonal [50], X-shaped [51][52][53][54], flower-shaped [55], H-shaped [56], hexagonal [55] and square [58].…”

In advanced optical communication systems, a photonic crystal (PC) based channel drop filter (CDF) and dense wavelength division multiplexer (DWDM) demultiplexer are essential components in the design of a complete DWDM system, which offers a high transmission data rate. In the present work, a novel PC, CDF filter and demultiplexer based on a ring resonator with a super ellipse shape is designed and analyzed. To design a high-performance device, the performance parameters of the proposed components, such as transmission efficiency, spectral line width, channel spacing, Q-factor and crosstalk, are investigated. The proposed CDF is designed to drop a resonant wavelength with a high quality factor of 3955, and the ring resonator design is extended to the demultiplexer. The demultiplexer is designed to drop the four resonant wavelengths of 1579.8 nm, 1582 nm, 1583.6 nm and 1574.9 nm, respectively. The observed high quality factor (3955), bandwidth (0.4 nm) and transmission efficiency (90%) of the proposed demultiplexer will support high-performance DWDM systems

“…The DAC structure consists of a PCRR, which is designed by removing an array of 7 × 7 dielectric rods. Scattering rods are placed at the corners of the ring resonators and waveguides with half the lattice constant in order to have a high-drop efficiency [19] and a reduced back reflection [20].…”

The future of telecommunication and optical communication networks is extremely focused on the design and development of photonic integrated circuits (PICs). Photonic crystals play the foremost role in realizing all optical integrated circuits. Every single optical component required to be integrated in PICs can be outlined based on the requirement of the application and can be obtained with the photonic band gap property of photonic crystals. Numerous works on different optical components has been done using photonic crystals. Among which, optical digital-to-analog converters (DACs) need to be explored and attended to incorporate into PICs. In this paper, photonic crystal-based 1-bit and 2-bit DACs, suitable for the photonic integrated circuits application, are proposed. Photonic crystal ring resonators and waveguides were integrated into the reported structures. The Kerr effect of the ring resonators has been utilized to provide an average error of 4.8477% for a 2-bit optical DAC. The devised structure provides an insertion loss of −5.5596 dB, with an overall dimension of 358 µm 2 . The DAC structures were simulated using finite difference time domain and plane wave expansion methods.

“…Meanwhile, optical demultiplexers are specialized devices engineered to separate a composite optical signal into its individual components, often based on their respective wavelengths, utilizing a combination of multiple filters. By extracting each channel separately, demultiplexers facilitate precise signal processing and analysis, thereby contributing to the maintenance of optimal network performance [4], [5].…”

This paper attempts to investigate the design of a modified Y-shaped demultiplexer based on photonic crystal. The designed structure is used to select four telecommunication wavelengths. In our design, four resonant cavities (RC)are utilized. A square lattice of silicon (Si) rods immersed in air matrix is used as a fundamental structure. Thus, our study is to investigate the effect of various design parameters on the output frequency. To simulate the performance of the proposed device, the Finite Difference Time Domain (FDTD) approach is used. The obtained results show that the average power transmission, quality factor, channel spacing, crosstalk, and full width at half maximum, are 99.925 %, 4638.785, 19.6 nm, from -40,119 to -24,316 dB, and 0.325nm, respectively.Additionally, the proposed demultiplexer is very compact with a total footprint of 269µm 2 , which is very suitable to be utilized in compact photonic integrated circuits (PIC).
