Abstract
Conference Title: 2015 IEEE Photonics Conference (IPC) Conference Start Date: 2015, Oct. 4 Conference End Date: 2015, Oct. 8 Conference Location: Reston, VA, USA The phase change dispersion during the surface plasmon wave coupling process was extracted experimentally using a slit-groove interferometer and validated through numerical simulation, enriching the fundamental understanding of plasmonic subwavelength optics on a chip.
