We present the concept of time-domain bound states in continuum. We show that a rapid judiciously-designed temporal modulation of the refractive index in a spatially homogenous medium gives rise to a bound state in time embedded in a continuum of wavenumbers. Mathematically, these bound states in the continuum (BIC) are analytic solutions of the Maxwell equations in time and one-dimensional space. Our results show the potential to extend known wave phenomena in space to the temporal domain, providing new avenues for light-matter interactions in time-varying media.

  1. Topologically protected edge states in time photonic crystals with chiral symmetry

    physics.optics 2025-01 conditional novelty 5.0 of 10

    Chiral-symmetric temporal photonic crystals host edge states whose eigenfrequencies are insensitive to disorder, unlike their time-reversal-symmetric counterparts.
