Abstract: Based on a novel phase-sieve method by in-plane interference
processes, a well-designed nonperiodic nanogroove array on gold surface is
proposed as a multifunctional and multi-output plasmonic meta-element
(MPM) for surface plasmon polariton waves. An MPM functions as a
plasmonic lens (PL) as well as a plasmonic array illuminator (PAI), and
another MPM acts as two PLs with an intersection angle of π/4 are
fabricated and validated by leakage radiation microscopy measurements.
Our proposed scheme with implemented functionalities could promote
potential applications in high density integrated optical circuits.
