Abstract
We design and simulate the waveguide Bragg grating pressure sensor on Boro float glass substrate. Rib waveguide structure is used for the design of pressure sensor, centered at 632.8 nm. The pressure sensor is simulated for a range from 5 to 80 MPa. Poly(methyl methacrylate) is used as the waveguiding material and air as the cladding surface. The rib waveguide is designed in RSoft tool using beam propagation method, and GratingMOD is used to create periodic perturbations on it. The pressure sensitivity as observed after simulation is 0.074 nm/MPa.
