“…The simulation has been done in a two-dimensional form and the structure's mesh size has been considered as equal to Δx = Δy = λ/16, where λ is the free space wavelength and has been considered as equal to 1550 nm. Thus, using the following formula, the time steps of the simulation are equal to Δt [24] Δt ≤ 1 c 1 Δx…”

“…Nkonde et al presented a silicon photoniccrystal waveguide composed of three different microcavities, and the three output ends for waveband de-multiplexing with the peak transmission at the three optical windows could reach 86.6%, 63.5%, and 97.7% [10]. The proposed structure by Seifouri M. et al can filter the central wavelength of 1548 nm with a transmission coefficient of over 95% [11]. A structure was made by Moloudian G. et al of air holes in a dielectric background [12].…”

“…Moreover, the microcavity near the back will be affected by the microcavity near the front, and the filtering efficiency will be reduced. To solve this problem, Fan [11] et al designed a dual-wavelength photonic crystal filter. Based on the above theoretical analysis, multi-wavelength and multi-channel photonic crystal filters are considered for the design.…”

Multi-wavelength and multi-channel photonic crystal filters are designed with different sizes considered by using a two-dimensional quadric lattice photonic crystal structure to solve the problems of a multi-channel filter with structure complexity, single-wavelength download, and channel interference. The designed filter consists of a waveguide, reflection wall, multimode microcavity, and output port. Each port can download three different wavelengths. In the communication band from 1.500 to 1.600 μm, the transmittance of each channel is greater than 90%, and the filtering efficiency is high. The size of the non-simplified filter is only 27 μm × 17 μm. On the premise of ensuring low loss transmittance (that is, the transmittance of each port is changed by no more than 10% at the wavelength from 1.5–1.6 μm), the size of the filter can reach 15 μm × 7 μm. This design will greatly reduce the overall structure size of the filter and is suitable for multiplexing and demultiplexing in WDM systems.

Novel Biosensor Detection of Tuberculosis Based on Photonic Band Gap Materials

et al. 2021

Tuberculosis is one of the most widespread infectious and deadliest diseases in the world. The death percentage is larger than that in the case of the current Coronavirus. Bio-photonic sensors represent a promising option for developing reliable, simple, and affordable tools for the effective detection of tuberculosis. In this paper, a novel design of an optical biosensor will be used as a tuberculosis detector based on a resonance cavity with high sensitivity in one-dimensional photonic crystals demonstrated theoretically. The results show that the increase of the defect layer thickness shifts the defect mode to a longer wavelength region. Besides, it is shifted to a shorter wavelength region via the increase of the incidence angle. The change in thickness of the defect layer and incident angle of light cause an optimization for our suggested structure and the sensitivity reaches 1390 nm/RIU. Our structure is very simple for industrial design.
