Abstract

TU-T SG15/Q2 has started a system-technology evaluation in support of next-generation of Passive Optical Networks beyond 50Gbit/s. One candidate solution is an intensity-modulated and direct-detection (IMDD) scheme with bit rates of 100Gbit/s/wavelength.

Surface plasmonic devices have revolutionized nano-imaging, quantum sensing, spectroscopy, electrocatalysis, and subwavelength photonic circuits. They serve as single-photon sources, enable transistor action, and enhance fluorescence. Surface plasmonics, arising from coherent light-matter interaction, also can initiate quantum entanglement, which is pivotal in quantum science. For example, interwoven with surface plasmons, continuous variable entanglement can extend quantum sensing beyond photon shot noise limits. Establishing entanglement across plasmonic media enables quantum communication within integrated circuitry. This frontier research promises transformative opportunities amidst challenges in nanoscale quantum communications.
