Paper Abstract

A technique was developed to achieve enhanced coherent anti-Stokes Raman scattering (CARS) imaging using selfassembled silica microspheres. In this study, a layer of optically transparent silica microspheres was self-assembled onto polymer grating samples to enhance the CARS signals. The highest enhancement of 12.5 was achieved using 6.1-μmdiameter microspheres for C-H molecule vibration. Finite-difference time-domain (FDTD) algorithm under the perfectly matched layer boundary condition was used to simulate the enhancement using silica microspheres of different diameters.
