A polymer based on fluorene, thiophene, and benzothiadazole as the donor-spacer-acceptor triad is covalently coupled to reduced graphene oxide (rGO) sheets via diazonium coupling with phenyl bromide, followed by Suzuki coupling. These polymer-graphen

We present a carbon nanotubes (CNTs) deposited photonic crystal fiber (PCF) featuring a Mach-Zehnder interferometer configuration for refractive index (RI) sensing applications. The high RI of the CNTs deposited on the surface of the PCF not only enh

We present a novel fiber optic sensor based on the assembly of a thin film of carbon nanotubes (CNTs) onto a short length of photonic crystal fiber (PCF) which is spliced between two single mode fibers (SMFs). The assembly of the thin film was achiev
