A pressure sensor based on two dimensional photonic crystal structure is presented. The structure considered for sensing is a lattice of air holes surrounded by semiconductor material. A waveguide with central microcavity is formed by filling air holes with semiconductor material. The sensing principle depends upon the shifting of central wavelength of peak towards higher wavelength region when the pressure is raised. The proposed pressure sensor can work in the range 0-5 GPa. Using this structure, two semiconductors, Si and GaAs, have been taken for analysis. It is found that shifting of resonance wavelength with pressure is more pronounced in GaAs than Si. In the dynamic range 0-5 GPa, sensitivity for sensor with Si is estimated as 1.674 nm/GPa while it is 17.00 nm/GPa for sensor with GaAs. The quality factor and figure of merit (FOM) is also found to be higher for GaAs sensor.

“…He presented the first explanation about the photonic crystal. Then, this field attracted visual attention in different applications such as chemical sensors [5,6], biosensors [7][8][9], filters [10,11], optical lenses [12], solar cells [13], and other applications [14][15][16][17][18][19][20][21]. Recently, the main challenge is how to use Nanomaterials with a very small size to create smart structures that can be used as complex and sophisticated devices [22][23][24].…”

A highly-sensitive remote temperature sensor based on Tamm resonance is proposed using a one-dimensional photonic crystal. The proposed structure is prism/Ag/Toluene/SiO 2 /(PSi 1 /PSi 2) N /Si. The transfer matrix method is used to discuss the interaction between the structure and the S-polarization of the incident radiation waves. We optimized the structure by studying the effect of the incident angle, the thickness of the first and second layers of the photonic crystal unit cell, the porosity of them, and the thickness of the toluene layer. High sensitivity, high signal-to-noise ratio, and very low resolution are achieved due to the coupling between the porous silicon photonic crystal properties and Tamm resonance that makes it very distinguished compared to previous works.
