چکیده
|
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.
