“…The PC is composed of a triangular lattice of air holes in a dielectric background. In the proposed structure, the refractive index of the 2D PC slab and the substrate (at the wavelength of 1.55 m  ) are 3.43 and 1.5, respectively [17]. The thicknesses of the 2D PC slab and the substrate are 479.74nm and 1050 , nm respectively.…”

“…A point defect embedded in the PC structure, that acts as a micro-cavity, can trap the light. So far, a few PC-based structures have been suggested for strain/stress [12][13][14][15], and pressure sensor [16][17][18][19][20][21][22][23][24].…”

“…In 2007, Stomeo et al [16] realized a force/pressure optical sensor by designing a bulk GaAs/AlGaAs photonic crystal microcavity operating in the wavelength range 1300-1400 nm. In 2007, Biallo et al [17] proposed a 2D PC microcavity (designed on a GaAs membrane) coupled to a PC waveguide to realise a highly sensitive pressure sensor and evaluated the change of the refractive index induced by the application of a force onto a sensing surface. In 2011, Tung et al [18] presented the theoretical and experimental investigations on the strain sensing effects of a 2D PC micro-cavity.…”

This paper reports the design and three dimensional (3D) simulation of a new photonic crystal (PC) pressure sensor. The device is constructed using a GaAs-based 2D PC slab on SiO2 substrate. The strain/stress simulations and also the spectral simulations are done using CST Studio Suite. In this investigation, the sensitivity of the proposed pressure sensor is calculated by considering the variation of the refractive index and also the deformation of the structure. The numerical results show that when pressure is applied, the refractive index variations cause an increment in the resonant wavelength of the transmission spectrum, but the deformation factor cause a decrease in the resonant wavelength. It has been shown that the relationship between the applied pressure and the resonant wavelength of the designed micro-cavity is linear. Based on the simulation results, the quality factor of the designed micro-cavity and the sensitivity of the pressure sensor are 2200 and 3.5 nm / GPa, respectively.

“…Optical sensing, especially biosensing, is one of the application fields most benefitted from the strengthening of light-matter interaction, since its principle relies on identifying substance changes on the basis of light-matter relations. Higher standards of sensitivity and resolution are enabled by the use of slow light in sensing devices (Biallo et al, 2007;Pedersen et al, 2008). Fig.…”
