BICs are not only of great theoretical interest, but have a wide range of practical applications, e.g. in the design of optical resonators. Here, we study this phenomenon in a new integrated nanophotonic element consisting of a single dielectric ridge terminating an abruptly ended slab waveguide. This structure can be considered as an on-chip analogue of the Gires-Tournois interferometer (GTI). We demonstrate that, in contrast to the conventional ","authors_text":"Dmitry A. Bykov, Evgeni A.
