Paper Abstract

Plasmonic and metasurface structures offer unique optical features such as sub-wavelength field confinement, unusual optical nonlinear/quantum properties and wavefront shaping for advanced light manipulation and development of novel and ultracompact optical devices [1]. On the other hand, optical fiber is very efficient in transmitting light, however, its functionality is somewhat limited by the dielectric material of the core, which has poor electronic, magneto-optical, and nonlinear-optical responses and has the dielectric diffraction limit. In this talk, I will review our recent research efforts on the study of “meta”-optical fiber by integrating metasurface and plasmonic nanostructures with optical fibers. I will discuss our development of novel and ultracompact in-fiber optical meta-devices such as an optical fiber color filter and metalens [2, 3]. I will also present the opportunity on using plasmonic nanowire probe on optical fiber for tip-enhanced Raman spectroscopy for bio/chemical sensing. These advanced “meta”-optical fibers open the path to revolutionary in-fiber optical imaging and sensing applications [4]. 1. Y. W. Huang, H. W. Lee, R. Sokhoyan, R. Pala, K. Thyagarajan, S. Han, D.
