摘要:Surface plasmons (SPs) propagating along the interface between metals and dielectrics are capable of
tailoring light matter interaction at the nanoscale, which emerges as a research frontier in nanophotonics. In
this talk, we introduce the recent progress of high capacity optical information storage and high throughput
on-chip information processing mediated by surface plasmons. Through the investigation of polarization-sensitive
plasmonic resonance in metallic nanorods and the subsequent photothermal reshaping mechanism, information can
be multiplexed in the multiple polarization orientations in the same spatial region. It enables optical recording with
orders of magnitude increased capacity as well as security. In addition, we show the throughput of information
processing by plasmonic nano-structures can be significantly increased.
