Driving Micro‐Objects Using Optical Force due to Fluorescence Emission From Molecules

Advanced Optical Materials, EarlyView.
Emission of fluorescence from a micro‐object in a specific direction is expected to generate an optical force driving the object in the opposite direction of the emission, like a rocket. To demonstrate this ‘photon‐driven micro‐rocket’, we prepared dye‐doped polymer micro‐object (PMO) one surface of which was covered with metallic film; the PMO ...

Toward Direct Laser Writing of Dual‐Layer Metasurfaces with the Plasmonic Phase‐Change Material In3SbTe2

Advanced Optical Materials, EarlyView.
A simple optical programming technique is developed for fabricating plasmonic nanoantennas in a dual‐layer metasurface by crystallizing the plasmonic phase‐change material In3SbTe2 from the top and through the substrate with a subsequent reamorphization step.

Optical Fiber Meta‐Tips Based on Partial‐Phase Control

Advanced Optical Materials, EarlyView.
Optical fibers working as beam splitters or focusing lens are demonstrated, with the aid of a metasurface integrated on the fiber end facet. Metasurfaces based on meta‐atoms featuring partial control of the phase are considered unleashing their potential.
