Abstract

This work presents an on-chip optical sensing system based on phase-shifted Bragg grating. The proposed design could be easily fabricated using ion exchange technology. The sensor geometry has been optimized using a finite difference time domain (FDTD) solver to achieve maximum sensitivity and figure of merit (FOM). FOM of 227.63 and a sensitivity of 343.1nm/RIU have been achieved for the water-based sensing system.
