Graphene oxide is a very attractive material for refractive index and humidity sensing due to its unique 2-D structure, which results in faster response times and improved sensitivity over alternative materials. In this paper, response of a graphene-oxide-coated long-period grating-based sensor to...

By white light contrast spectroscopy, we have successfully identified number of graphene oxide (GO) layers (10 layers) and obtained a new refractive index of GO sheets (10 layers) of nGO=1.2–0.24i. For few layers (10 layers) GO sheets, both the contrast at 580nm wavelength and the Raman...

Picometrology is applied to measure the refractive index of graphene on thermal oxide on silicon. The refractive index varies from ñg = 2.4-1.0i at 532 nm to ñg = 3.0-1.4i at 633 nm at room temperature. The dispersion is five times stronger than bulk graphite (2.67- 1.34i to 2.73...
The optical response of a graphene oxide integrated silicon micro-ring resonator (GOMRR) to a range of vapour phase Volatile Organic Compounds (VOCs) is reported. The response of the GOMRR to all but one (hexane) of the VOCs tested is significantly higher than that of the uncoated (control...
Due to the graphene oxide (GO), the intensity of the confined electric field surrounding the sensing layer can be enhanced, the sensitivity of refractive index (RI) of the graphene oxide/silver SPR sensor reached 3311 nm/RIU in the RI range of 1.3334–1.3731 compared with 2875 nm/RIU ...
