Presentation / Conference Contribution
Dissanayake, K., Ghosh, S., Binetti, L., Rente, B., Alwis, L., Sun, T., & Grattan, K. (2019, July). External Refractive Index Sensitivity Enhancement of a Long Period Grating by Graphene Oxide Overlay. Presented at Latin Americal Workshop on Optical Fiber

In this paper, an external refractive index sensor is presented based on a graphene oxide coated long period grating and based on creating a stable graphene oxide coating on the fibre surface using a drop casting technique. The wavelength shift sensi... Read More about External Refractive Index Sensitivity Enhancement of a Long Period Grating by Graphene Oxide Overlay.
