Boosting the Figure Of Merit of LSPR-based refractive index sensing by phase-sensitive measurements

, 2012
Localized surface plasmon resonances possess very interesting properties for a wide variety of sensing applications. In many of the existing applications only the intensity of the reflected or transmitted signals is taken into account, while the phase ...

Large dynamic resonance transition between surface plasmon and localized surface plasmon modes

Optics Express, 2010
We present resonant terahertz transmission in a composite plasmonic film comprised of an array of subwavelength metallic patches and semiconductor holes. A large dynamic transition between a dipolar localized surface plasmon mode and a surface plasmon resonance near 0.8 THz is observed under near infrared optical excitation.
