Abstract

We demonstrate that super-resolution imaging of specimens containing sub-diffraction-limited features is feasible by using dielectric microwires fabricated through capillary force lithography followed by photopatterning. As supplementary micron scale cylindrical lenses, we fabricated uniform-sized microwires with and 5 and 10 μm diameters and refractive index ∼1.3-1.6. The microwires are placed in contact with the specimen to collect the information of the sub-wavelength features of the specimen and transmit them to the far-field with magnification enabling imaging with two-fold resolution improvement. Potential applications of our imaging technique include biological imaging, microfluidics, and nanophotonics applications.
