Abstract
Bound states in the continuum (BICs) can be observed in photonic crystal slabs embedded in low refractive index surroundings that makes challenging their realization. Here we propose a configuration implemented on a high refractive index bulk substrate with a one-dimensional grating positioned on a distributed Bragg reflector (DBR). Judiciously designed DBR reflects all diffraction orders induced by the grating entirely eliminating radiative losses. The configuration enables a high degree of design freedom facilitating the realization of very high quality factor cavities in conventional all-semiconductor technology.
