Bound States in the Continuum and Unidirectional Guided Resonances Enabled by Competing Fourier Harmonics near the Fourth Stop Band
Sun-Goo Lee, Wook-Jae Lee
Bound states in the continuum (BICs) and unidirectional guided resonances (UGRs) are singular radiative eigenstates in planar photonic lattices characterized by complete or directi…

Merging bound states in the continuum at third-order point enabled by controlling Fourier harmonic components in lattice parameters
Sun-Goo Lee, Seong-Han Kim, Wook-Jae Lee
Recent studies have demonstrated that ultrahigh- resonances, which are robust to fabrication imperfections, can be realized by merging multiple bound states in the continuum (BI…

Transition from quasi-unidirectional to unidirectional guided resonances in leaky-mode photonic lattices
Sun-Goo Lee, Seong-Han Kim, Wook-Jae Lee
Unidirectional light emission from planar photonic structures is highly advantageous for a wide range of optoelectronic applications. Recently, it has been demonstrated that unidir…
