Abstract: (915 Views)
In this paper, a new pressure sensor in order to create a high-sensitivity structure by using two-dimensional photonic crystal structures is designed and simulated. To create the structure, a main waveguide is used to transmit light from the input in combination with a ring resonator as well as the output waveguide. The maximum sensitivity of the sensor at a pressure of 1 GPa is equal to 10 nm/GPa and the best quality factor at a pressure of 3 GPa is equal to 2122. Also, the size of the structure is about 272 (μm)^2, which is very small compared to structures in this field and has high simplicity and flexibility. PWE method has been used to extract the photonic band gap and also FDTD method has been used to extract the output spectra of the designed structures.
