Merging multiple microprocessors with high-speed optical networks has been
considered a promising strategy for the improvement of overall computation power.
However, the loss of the optical communication bandwidth is inevitable when
interfacing between optical and electronic components. Here we present an on-chip
plasmonic switching device consisting of a two-dimensional (2D) disordered array
of nanoholes on a thin metal film that can provide multiple-input and
multiple-output channels for transferring information from a photonic to an
electronic platform. In this device, the surface plasmon polaritons (SPPs)
generated at individual nanoholes become uncorrelated on their way to the
detection channel due to random multiple scattering. We exploit this
decorrelation effect to use individual nanoholes as independent antennas, and
demonstrated that more than 40 far-field incident channels can be delivered
simultaneously to the SPP channels, an order of magnitude improvement over
conventional 2D patterned devices.
