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 energy level diagram of PCs is similar to the electronic energy level diagram in crystal physics. PCs can be used to develop all kinds of sensors, such as biochemical sensors, [6][7][8] mechanical sensors, [9,10] temperature sensors, [11,12] refractive index sensors, [13,14] and gas sensors; [15,16] optical modulation devices, such as optical fibers, [17,18] waveguides, [19][20][21][22][23][24] optical filters, [25][26][27] and microcavities; [28][29][30] and single-photon detectors.

Photonic crystal structures have excellent optical properties, so they are widely studied in conventional optical materials. Recent research shows high-temperature superconducting periodic structures have natural photonic crystal features and are favourable candidates for single-photon detection. Considering that superconductors have completely different properties from conventional optical materials, we study the energy level diagram and mid-infrared 3–5 μm transmission spectrum of two-dimensional superconducting photonic crystals in both superconducting and quenched states with the finite element method. The energy level diagram of the circular crystal column superconducting structure shows that the structure has a large band gap width in both states. At the same fill factor, the circular crystal column superconducting structure has a larger band gap width than the other structures. For lattice structures, the zero transmission point of the square lattice structure is robust to the incident angle and environmental temperature. Our research has guiding significance for the design of new material photonic crystals, photon modulation and detection.

This paper reviews all-optical analog to digital converters (OADCs) based on the photonic crystal. They are nonlinear applications and are used in all-optical data processing systems. They are consisting of one input (i.e., continuous analog optical signal) and two or five outputs (i.e., binary code). Most of these structures have two operation steps. The first one is a nonlinear demultiplexer followed by second stage that has an optical coder. The demultiplexer creates the discrete levels for the continuous optical input signal; then the optical coder generates output bits. There are two techniques to design OADC, ring and cavity resonators. All OADCs structures use the finite difference time domain (FDTD) and plane wave expansion (PWE) analysis methods. The paper presents a comparison between the different designs in the literature for both the ring and cavity resonators using the RSOFT simulator followed by the challenges and some novel trends.
