Abstract

In this paper, we design and simulate a two-dimensional photonic crystal MZI for pressure sensing with a high sensitivity. The sensor is formed by silicon rods of a rectangular lattice distributed in air wafer; when the pressure is applied in an area of rods situated between the Y branch waveguides of MZI, the sensitivity achieved a very high value which is 22.3667 nm/GPa compared to that obtained when the pressure was applied over the entire surface of the sensor structure in which the sensitivity reached 6.36 nm/GPa.
