Bound states in the continuum in photonic structures

In quantum physics, a bound state is a quantum state of a particle subject to a potential such that the particle has a tendency to remain localized in one or more regions of space. The potential may be external or it may be the result of the presence of another particle; in the latter case, one can equivalently define a bound state as a state representing two or more particles whose interaction energy exceeds the total energy of each separate particle. One consequence is that, given a pot… WebThe realization of an efficient optical sensor based on a photonic crystal metasurface supporting bound states in the continuum is reported.

BICs are waves that remain perfectly confined, or bound, in an open system. Conventional waves in an open system escape, but BICs defy this norm — they stay localized and do not escape despite having open pathways to do so.
