Profile
Career and documented record
Strong optical coupling is normally a local effect, limited by fields that decay quickly away from a resonator. In 2025, Danqing Wang first- and co-corresponding-authored a Nature Communications study using an epsilon-near-zero material to extend coupling across hundreds of micrometres.
The reported distance is roughly three orders of magnitude beyond conventional near-field coupling lengths. That changes the architecture available to photonic systems: components need not sit nearly on top of one another to share a coherent optical interaction.
The experiment is a platform result rather than a finished device. Its importance lies in showing that a carefully engineered electromagnetic medium can make a usually local quantum-optical interaction spatially collective.

Why Danqing Wang is on the list
Wang is selected for a clean physical result with a large change in operating scale and clear first-author leadership. The study opens design space across photonics without relying on an unbuilt application for its significance.

The work in its field
Long-range coupling could let separated emitters and resonators behave as one optical system, but only if coherence survives material loss and fabrication variation.

First- and co-corresponding-authored strong optical coupling over hundreds of micrometres.
Verified scientific impact
12.3 / 15
A large, peer-reviewed change in coupling distance creates a notable platform result in nanophotonics.
Originality and distinction
8.7 / 10
The distinction lies in using an epsilon-near-zero optical environment to mediate collective coupling far beyond the near field.
Field influence
8.4 / 10
Within photonics, the work matters because it shifts a live question in epsilon-near-zero optical coupling rather than merely attracting attention.
