| Abstract | Here, we report a tunable plasmonic crystal (tPLC), where the polaritonic mode of a metallic array can be combined with the photonic mode of a hole array in a dielectric slab for achieving negative refraction and still possess an extra degree of freedom for tuning the tPLC as a superlens to operate at different frequencies. We numerically demonstrate the tunability of a single planar tPLC slab for subwavelength imaging (full width at half maximum, $0.38\ensuremath{\lambda}\ensuremath{\sim}0.42\ensuremath{\lambda}$) by just varying the fluid in the hole array, thereby enabling the realization of ultracompact tunable superlens and paving the way for a class of unique lens. |
