Abstract
In this paper, we designed a pressure sensor based on a linear waveguide coupled with nano-ring resonator using two-dimensional photonic crystals. The ring resonator minimizes the external parameters effect such as temperature, humidity, etc. The proposed pressure sensor works on the principle of resonance wavelength. Due to the applied pressure, the refractive index of a sensor is changed and thus resonance wavelength of a sensor is also shifted. The simulation results show that the resonance wavelength of a pressure sensor shifts between the ranges 1.3–1.9 µm. The quality factor of sensor is 5179 and sensitivity of a sensor is 7.7 nm/GPa. Pressure sensor has good resolution in the range of nN and minimum detectable pressure is 0.10 nN range. The band-gap of structure is calculated using plane wave expansion (PWE) method and all other computation work such as transmission power, electric field distribution are performed using finite difference time domain (FDTD) method.
