Optical tweezers with enhanced efficiency based on laser-structured substrates
Full text linkWe present an optical nanotrapping setup that exhibits enhanced efficiency,
based on localized plasmonic fields around sharp metallic features. The
substrates consist of laser-structured silicon wafers with quasi-ordered
microspikes on the surface, coated with a thin silver layer. The resulting
optical traps show orders of magnitude enhancement of the trapping force and
the effective quality factor
