A photonic-crystal optical antenna for extremely large local-field enhancement [PDF]
, 2010 We propose a novel design of an all-dielectric optical antenna based on photonic-band-gap confinement. Specifically, we have engineered the photonic-crystal dipole mode to have broad spectral response (Q ~70) and well-directed vertical-radiation by ...

Controlled fiber core mode and surface mode interaction for enhanced SERS performance
Optics Express, 2022 Three-dimensional surface-enhanced Raman scattering (SERS) platform based on microstructure fibers has many advantages for rapid liquid detection due to its microfluidic channels and light guidance. The fiber mode field distribution determines the light-analyte interaction strength but has rarely been studied in SERS applications.
