| Abstract: | A novel nano-sensing configuration was proposed,whose mechanism was based on the influence of optical energy distribution variations on double slot waveguide by nanometer displacements.Results from numerical simulation with the finite difference time domain method show that the sensor could response to displacement less than one nanometers and the measuring range could extend to 100 nm.It's highly promising for physical quantity measurement with high sensitivity in the future,such as displacement,pressure a... |
