چکیده مقاله
Recently leaky surface plasmon polaritons excited on top of a thin gold stripe, using the Kretschmann configuration, have attracted more attention due to the exciting possibilities in nano particle trapping, sensing and in situ monitoring applications Here, a tapered stripe is proposed that can enhance the efficiency of photon plasmon coupling by gradually focusing the surface plasmon polaritons at the near end of the stripe In this paper, using the three dimensional finite difference time domain numerical method 3D FDTD , effects of exciting and tapering angles on the excited modes are investigated For example, Simulations predict that when the tapering angle is about 45° the maximum mode enhancement after prppagating 8µm along the stripe, is improved more than 60 percent as compared to the un tapered structure The proposed structure benefits from low power consumption and simply and inexpensively integration into lab on a chip devices I believe these features can be used to enhance the efficiency of the Stripe based plasmonic optophoresis systems; introducing a promising candidate to develop integrated optical manipulation chips especially for biological applications
