摘要：
Instead of the conventional method of monitoring the transmitted light through a ferrofluid film, in this study we use ferrofluids as the guiding layer in a double metal-cladding optical waveguide structure, and measure the reflected light intensity to investigate the chain formation speed (switching speed) in ferrofluids. We conclude that the ultrahigh-order mode-induced optical trapping effect may be the main reason for the observed fast switching time which is increased by at least three orders of magnitude when a magnetic field was applied.
