An all-optical modulator based on a graphene–plasmonic slot waveguide at 1550 nm
Applied Physics Express, 2019 An all-optical modulator with high modulation efficiency based on a graphene-plasmonic slot waveguide structure is proposed. The modulation efficiency is enhanced by the strong interaction between the light and the graphene–plasmonic structure.

Localized Field Enhancements in Guided and Defect Modes of a Periodic Slot Waveguide
IEEE Photonics Journal, 2011 We present a periodic slot waveguide for achieving enhanced light–matter interaction that provides significant localized field and power density enhancements over traditional slot waveguides. The basic structure is based on a slot waveguide with 1-

Advanced Science, EarlyView.This work demonstrates a receiver‐transmitter‐integrated metasurface that decomposes an incident wave into orthogonal components and routes them into separate channels. Inspired by a “Wheel‐of‐Fortune” mechanism, it enables independent control over the amplitude, phase, and polarization of the transmitted wave.

Advanced Science, EarlyView.Mode splitting in meta‐waveguide microring resonators (MWMRs) effectively suppresses baseline drift and measurement noise while maintaining high refractive‐index sensitivity. This reflection‐induced mode splitting strategy enables quantitative detection of ultra‐weak surface perturbations and establishes MWMRs as a robust, drift‐immune platform for ...
