Abstract
We report near-field focusing phenomena depending on the radius of curvature (ROC) and the refractive index of a microscale solid immersion lens (m-SIL) by finite-difference time-domain (FDTD) calculation. We show the clear effect of the ROC and the refractive index on the focal length and the focal-spot size, indicating the estimated resolution of the combined optical system.
