“…Due to their photonic band gap (PBG) region, photonic crystals (PhCs) have excellent ability to confine and control the light waves inside compact waveguides [1,2]; therefore, they are very promising structures to design compact optical devices such as multiplexers [3,4] and demultiplexers [5][6][7][8].…”

Abstract-The article analyzes a nine-channel Wavelength Division Demultiplexer based on a twodimensional photonic crystal lattice. In the design of the device, defects and air holes are shifted in the resonant cavities: by changing characteristics such as radii of defects, distance between them and position of defects. A compact optical filter circuit is designed with a 1 nm channel spacing. The properties of these devices are investigated using finite-difference time-domain method. The resonant wavelengths of nine channel demultiplexers are 1481. 4, 1503.7, 1526.6, 1538.4, 1550.3, 1562.3, 1574.7, 1587.2 and 1612.9 nm. The value of transmission efficiency for channels was obtained in 79-96% range. In addition, the maximum value of crosstalk and average quality factor for channels were calculated −11.3 dB and 2000, respectively. The overall size of the structure is small (11.3 µm × 15.3 µm) which is suitable for photonic integrated circuits and optical communication network applications.

A new proposal for eight-channel optical demultiplexer based on photonic crystal resonant cavities

In this paper, we used the novel defective resonant cavities to design an eight-channel photonic crystal demultiplexer. We showed that by choosing appropriate values for the width of the resonant cavity, the desired wavelengths can be separated. The proposed platform has a square lattice of dielectric rods immersed in air. The value of transmission efficiency for channels was obtained in 94−99 % range. In addition, the maximum value of crosstalk and average quality factor for channels were calculated -11.2 dB and 2200, respectively.

“…It has been shown that combining hybrid PhC with conventional waveguide structures results in high efficiency ultra-compact waveguide bends, splitters and optical filters with controllable quality factor, free spectral range and full width at half maximum [27][28][29]. By placing a low loss resonant ring at waveguide intersection, we can realize L-shaped bends and T-shaped power splitters [30][31]. For T-shaped splitters the transmission window can be widened by changing the ring size.…”

“…They also proposed a T-shaped channel drop filter based on PhCRRs and investigated the effect of different parameters on switching wavelength [33]. They found that the dielectric constant of the inner rods and coupling rods is a main parameter for tuning the filter [31]. Multichannel-drop filter using PhCRR is the most recent work done by Djavid and Abrishamian [32].…”
