Bound states in the continuum (BIC) accompanied by avoided crossings in leaky-mode photonic lattices
Nanophotonics, 2020 When two nonorthogonal resonances are coupled to the same radiation channel, avoided crossing arises and a bound state in the continuum (BIC) appears with appropriate conditions in parametric space. This paper presents numerical and analytical results on

Metalenses Integrated Photonics
, 2023 This thesis investigates the optical metasurfaces utilized for lensing (metalens) and their potential to integrate with photonic circuits. In recent years, a plethora of studies have been done on metalenses, especially in the visible region. However, there are still rooms to discover the metalenses working in the mid-IR and ultraviolet (UV) spectra ...
