The observation of four-wave mixing(FWM) in single-walled carbon nanotubes(SWCNTs) deposited around a tilted fiber Bragg grating (TFBG) has been demonstrated. A thin, floating SWCNTfilm is manually wrapped around the outer cladding of the fiber and FWM occurs between two core-guided laser signals by TFBG-induced interaction of the core mode and cladding modes. The effective nonlinear coefficient is calculated to be 1.8 × 103 W−1 Km−1. The wavelength of generated idlers is tunable with a range of 7.8 nm.
