We demonstrate ultrafast modulation of the coupling efficiency of free-space radiation to a surface plasmon polariton mode on a gold film with a PMMA grating overlayer over a broad range of wavelengths 540–700 nm . We observe modulation magnitudes

Near-infrared pump/visible probe measurements on gold gratings demonstrate picosecond control of grating assisted coupling to surface plasmon polaritons. On-off switching ratios as large as 5.3 dB are possible.

The barriers physicians face when providing care to victims of domestic violence are well detailed in the literature, but few studies provide insight into how physicians overcome these barriers. Our goal was to describe the domestic violence interven
