Abstract

A layer by layer (LbL) coating made of polyethyleneimine (PEI) and graphene oxide (GO) is deposited onto an optical fiber ethanol sensor based on lossy mode resonances (LMR) in order to improve its response. The new sensor including the PEI/GO coating shows a better linearity and a sensitivity four times higher than the sensor without the coating. To our knowledge, this is the first time that a LbL coating made of PEI and GO is included in an optical fiber sensor based on LMR.
