Researchers demonstrate active control of exceptional points (EPs) chirality using exceptional-line metasurfaces. This method allows for light-induced loss to switch chirality, enabling on-chip integration for advanced electronic applications.

Area of Science:

  • Non-Hermitian physics
  • Metasurface engineering
  • Wave phenomena

Background:

  • Exceptional points (EPs) are degeneracies in non-Hermitian systems with implications for wave phenomena.
  • Chiral EPs offer unique effects like loss-induced transparency and enhanced sensing.
  • Previous methods for inducing chiral EPs required fixed structures and active gains, limiting on-chip applications.

Purpose of the Study:

  • To demonstrate active, in-situ control of exceptional points (EPs) chirality.
  • To develop a method for on-chip integration of chiral EPs.
  • To investigate light-induced modulation of EPs chirality.

Main Methods:

  • Fabrication of an exceptional-line metasurface.
  • Utilizing light-induced loss for selective chirality inversion.
