Profile Summary

Dr. Xiaoli Dai has made significant contributions to the field of optics and photonics, particularly in the area of waveguide-based sensors and interference patterns. One of her notable works involves developing a chemical sensor using Bragg grating-based optical ridge waveguides with a polydimethylsiloxane (PDMS) top layer. This sensor is highly sensitive to organic compounds and uses evanescent coupling to detect changes in the refractive index and absorption spectrum of the PDMS layer1.
