碩博專討演講公告
題目:
Nanophotonics in sensing, nonlinear optics, and metadevices
主講人:蕭惠心 教授
現職:國立臺灣師範大學 光電工程系 副教授
內容摘要:
Plasmonic nanostructures with their unique ability in localizing electromagnetic fields into small volumes have led to a great diversity of applications. We have utilized various designs to study plasmonic thermal emitters, surface-enhanced Raman scattering substrate, light absorption in photovoltaics, nonlinear frequency conversion, etc. In addition to strong field confinement, those nano-scatterers are capable of manipulating the phase response of the scattering light, which provides additional degree of freedom to accomplish polarization control and wavefront shaping. This leads to the field of metasurfaces developing various resonant mechanisms to achieve a phase coverage ranging from 0 to 2π. These metasurfaces are applied to demonstrate ultrathin and lightweight optical meta-devices such as achromatic meta-lenses and versatile polarization converters.
