Multi-mode Photonic Time Crystals Based on Time-Modulated Metasurface Waveguides

M. S. Mirmoosa, V. Asadchy, X. Wang, Z. Li

Time modulation of metasurface waveguides creates tilted intermodal band gaps in photonic time crystals, controllable by modulation phase.

Claims

C1strongest claim

temporal modulation in this platform gives rise not only to conventional intramodal band gaps associated with same-branch coupling, but also to tilted intermodal band gaps originating from coupling between different guided-mode branches... the modulation phase difference provides an effective symmetry-control parameter: by exploiting temporal glide symmetry, one can selectively suppress or enhance gap opening

C2weakest assumption

The metasurface waveguide remains impenetrable and supports the assumed guided surface and higher-order volume modes under the proposed time modulation without significant losses or fabrication imperfections that would close the intermodal gaps.

C3one line summary

Time-modulated metasurface waveguides enable multimode photonic time crystals with intramodal and tilted intermodal band gaps that support directional amplification and symmetry-based gap control.
