Title : Nanoplasmonics enabled multi-dimensional optical multiplexing

Abstract:

The electromagnetic radiation in the vicinity of metallic nanoparticles or nanostructures can be concentrated and confined to a region with sizes far smaller than the wavelength. Consequently, the augmented electric fields can lead to a variety of amplified photophysical or photochemical processes, underpinning tremendous appealing optical applications. Moreover, the dispersion of nanoplasmonics can be tailored to manipulate nanoscale light matter interaction to introduce advanced functionalities. In particular, femtosecond laser beam can induce enormous photothermal effects and even permanent shape transitions. In this talk, we present the recent progresses towards ultra-high capacity multi-dimensional optical memories. This is achieved through multiplexing information in the physical domain of the writing beams through tailoring the interaction between a tightly focused pulsed laser beam and nanoplasmonic materials. Amplitude, polarization, wavelength, wavevector and orbital angular momentum represent the basic dimensions over which we describe and manipulate light’s wavefronts, can be utilized to multiplex information in the volume of focal spots. By circumventing the diffraction limit, multi-dimensional optical storage paves the new way to next generation big data technologies.
