Recently, we show a method of color printing on nanoimprinted plasmonic metasurfaces using laser post-writing. Laser pulses induce transient local heat generation that leads to melting and reshaping of the imprinted nanostructures [1]. Depending on the laser pulse energy density, different surface morphologies that support different plasmonic resonances can be created. This technology creates a laser printer capable of producing color images with a resolution up to 127,000 DPI. With tailored trains of laser pulses, multiple optical states are flatiron onto the metasurface film with a nanoscale controlling. Thus, this diffraction-limited-resolution optical writing process can be further used to demonstrate a variety of applications in addition to large-area structural color printing. Multi-focus Fresnel zone plates with subwavelength focus, and more meta-surfaces different functions, such as spectroscope filters, Raman substrates and biosensors are also applicable.
