# Harnessing optical bound states in the continuum for ultrafast, reconfigurable, long-range photonic networks

## TL;DR

This paper explores using BICs to create fast, adjustable, and long-range photonic networks for advanced optical communication.

## Contribution

The paper introduces BIC metasurfaces for ultrafast, reconfigurable photonic coupling between resonators.

## Key findings

- BIC metasurfaces enable two-dimensional coupling between resonators in arbitrary positions.
- The system allows for ultrafast all-optical control of photonic networks.
- Dynamic tunability is achieved through BICs for long-range photonic interactions.

## Abstract

Bound states in the continuum (BICs) provide a route to strong, long-range photonic coupling with dynamic tunability. Recent advances demonstrate that BIC metasurfaces enable reconfigurable two-dimensional coupling between arbitrarily positioned resonators, with the added capability of ultrafast all-optical control.
