We present our technique to characterize the third-order nonlinear optical properties of organic dyes in our previously introduced integrated liquid-core optical fiber (i-LCOF) platform. i-LCOF is filled with the solution of the organic dyes, and the change in the laser pulse spectral width due to self-phase modulation is investigated. The measurements are done at 1550 nm using a mode-locked femtosecond fiber laser. The solution/laser interaction length is long (∼50 cm), which removes the need for high-power pump pulses. This methodis fast, simple, and can be extended to the characterization of other nanoscale particles such as quantum dots and plasmonic metal nanoparticles in solutions.
