“…The necessary functional parameters of our designed temperature sensor are compared with the already mentioned sensors, which are summarized in Table 2. It indicates that the dynamic range, quality factor (Q) = λ0/Δλ , and sensitivity (S) = ∂λ /∂T of the proposed temperature sensor are better than those of the previously existing sensor [25,27,28,29,30,31,32].…”

“…The detection operation of an all-optical temperature sensor is based on the refractive index variation as a function of the thermo-optical effect. The refractive index will be modi ed according to the temperature, which allows the photonic band gap and the center wavelength of the structure to be changed, and this variation is given as [25]: n 0 is the refractive index of the medium at zero temperature (0°C), α is the thermo-optical coe cient is given by 2.4×10 − 4 /°C for silicon [26] and ∆T is the temperature difference.…”

In our work, we propose a novel temperature sensor design based on a two-dimensional (2D) photonic crystal resonant cavity structure designed to detect and monitor temperature under very harsh environmental conditions from 0 °C to 500 ºC. The sensitivity of the proposed structure is 109.8 pm/ºC, an ultra-high quality factor, high transmission efficiency and ultra-compact size. The characteristics of the proposed sensor under different temperatures are simulated using the Plane Wave Expansion (PWE) method and Finite Difference Time Domain (FDTD) method to calculate, respectively, the Photonic Band Gap (PBG) and transmission efficiency. The results obtained show that the wavelength of the resonant cavity increases linearly with increasing temperature. Our sensor is suitable for applications based on nanotechnology.

In this paper we investigate a new design of high sensitivity photonic crystal temperature sensor (PCTS). A square lattice of silicon (Si) rods immersed in air matrix is used as a basic structure. The designed sensor consists of two inline quasi-waveguides which are coupled to a resonant cavity (RC). The sensing principle is based on Si refractive index change caused by the variation of the temperatures over a range from 0 to 80 • C. This variation leads to an important shift in the resonance wavelength. The performance of the suggested temperature sensor has been analyzed and studied using finite-difference time domain (FDTD) method. The results show that our designed structure offers a high sensibility of 93, 61 pm/ • C and quality factor of 2506.5. Its structure is very compact with total size 115.422 µm 2 , which is suitable for nanotechnology based sensing applications.

“…Some novel designs such as thermally actuated interferometric sensors have been reported based on device fabricated with PDMS [71], long period grating fiber sensors with high temperature sensitivity [72,73] and designs with photonic crystals [74,75] and plasmonic nanostructures [76]. These novel designs are complicated to fabricate and may not be suitable for a simple, quick temperature measurement.…”

Multi-microgratings are defined as arrays of one-dimensional diffraction gratings inscribed inside similarly shaped cells and then arrayed in a two-dimensional periodic fashion. Due to the high number of spatial periodicities, these structures form intricate diffraction patterns. A meticulous understanding on how the diffraction patterns form and what their optical properties are has not previously been studied and it is necessary in order to be able to exploit these properties in a variety of applications. A theoretical model of these
