Thermal relaxation trimming for enhancement of extinction ratio in electro-optic polymer Mach-Zehnder modulators
We propose and demonstrate a trimming method to enhance extinction ratio in an electro-optic (EO) polymer modulator with a Mach-Zehnder interferometer structure. In order to adjust the power splitting...

Experimental evidence of mode-selective evanescent power coupling at telecommunication frequencies with efficiencies up to 75% from a tapered optical fiber to a metal nanoparticle plasmon waveguide is presented. The waveguide consists of a two-dimensional square lattice of lithographically defined Au nanoparticles on an optically thin silicon membrane. The dispersion and attenuation properties of the waveguide are analyzed using the fiber taper. The high efficiency of power transfer into these waveguides solves the coupling problem between conventional optics and plasmonic devices and could lead to the development of highly efficient plasmonic sensors and optical switches. ©2005 American Institute of Physics
