Observation of bound states in the continuum embedded in symmetry bandgaps
Alexander Cerjan, Christina Jörg, Sachin Vaidya +5
In the last decade, symmetry-protected bound states in the continuum (BICs) have proven to be an important design principle for creating and enhancing devices reliant upon states w…

Point-Defect-Localized Bound States in the Continuum in Photonic Crystals and Structured Fibers
Sachin Vaidya, Wladimir A. Benalcazar, Alexander Cerjan +1
We show that point defects in two-dimensional photonic crystals can support bound states in the continuum (BICs). The mechanism of confinement is a symmetry mismatch between the de…
