This paper proposes a novel pressure sensor utilizing a two-dimensional photonic crystal (2DPC) based on a ring resonator design. The sensor consists of a square ring resonator that is connected to two photonic crystal waveguides. The photonic crystal is comprised of a square lattice of circular Silicon dielectric rods with air serving as a background. The proposed sensor operates within a pressure range of 0 to 6 GPa, corresponding to a wavelength range of 1554 nm to 1569 nm. The band structures and transmission characteristics of the proposed sensor are studied using the plane wave expansion (PWE) and finite-difference time-domain (FDTD) methods. The normalized transmission spectra of the sensor are observed by varying parameters such as the refractive index, radius, lattice constant, and pressure value, resulting in corresponding wavelength shifts. The proposed sensor design offers a compact size, a wide dynamic range of 6 GPa pressure, and a high sensitivity of 3 nm/GPa. These properties make it highly suitable for a range of applications such as high-pressure or stress-sensing, medical applications, and long pipeline strain monitoring.

This review summarizes recent advances in sensors based on photonic crystal technologies for biomedical sensing applications. Photonic crystal sensing offers enormous promise due to their clear benefits in sensitivity, stability, compactness, portability. This work discusses several photonic crystal structures, such as photonic crystal waveguides, cavities, and photonic crystal fiber for biomedical sensing applications. The uniqueness, measurement technique, and biosensing properties of each type of these structures are discussed. Furthermore, manufacturing and functionally relevant properties that include design simplicity, compactness, and multi-wavelength operation are also reviewed. They are explored, organized, and compared using the most recent related literature in this field. Finally, a brief of novel trends has been introduced.INDEX TERMS Biomedical sensors, photonic crystals, photonic crystal fiber.

“…Hence, PhC nanocavities with high Q factor and sensitivity (S) are preferred for sensing applications. In addition, the optical mode should be tightly confined in order to obtain a high Q, whereas the optical mode should be distributed into more target analytes in order to obtain a higher S. It has been observed that high-Q PhC nanocavities are widely used as photonic sensors to detect gases [9][10][11][12], solutions [13,14], biomolecules and chemicals [15], electric fields [16,17], and nano-pressure and temperature [18,19] because of the light-matter interaction between the optical fields and the analytes. However, in order to enhance the sensing performances, such as sensitivity, quality factor, and detection limit (DL), all designed PhC cavity structures have been used.…”

The optical properties of point-defect nanocavities implemented on elliptical-hole planar photonic crystal (EPhC) have been investigated for mid-infrared liquid sensing application. The EPhC nanocavities are composed of silicon planar photonic crystals with a triangular lattice of elliptical air holes, which do not require sophisticated design and high fabrication resolution. The numerical results show that the quality factor and the mode volume of the EPhC nanocavities increase exponentially with an increase in the ellipticity of the air holes. The Q factor is increased by a factor as large as 38 and 26 for H1 and L3 EPhC nanocavities, respectively, with a small mode volume by finely optimizing the EPhC nanocavities. Furthermore, the transmission spectrum of the optimized EPhC nanocavities shows that the variation in the refractive index that is used in the coating of the EPhC nanocavities induces a shift in the resonant wavelength of the nanocavity modes, thus allowing the precision measurement of liquid. In addition, a point-defect EPhC nanocavity with a sensitivity of 285 nm/refractive index unit (RIU) and a detection limit of 10−4 RIU are demonstrated. Therefore, these results suggest that the designed EPhC nanocavities are considered as a promising platform for mid-infrared liquid sensor devices with small detection volumes.
