Bound states in the continuum waveguide
Webloci of the bound states is sensitive to several design parameters, allowing bound states to exist for a broad range of angular directions and wavelengths and suggesting applications in filtering and sensing. Bound states in the continuum (BICs) are radiationless modes that exist in the part of the spectrum that corresponds to the continuum. WebSep 28, 2024 · In this work, we combine a CQD film with an array of titanium dioxide (TiO2) nanoantennas to achieve lasing via bound states in the continuum (BICs), which are symmetry-protected cavity modes with giant quality factors. Here, the BICs arise from slab waveguide modes in the planar film, coupled to the periodic nanoantenna array.
