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…
Merging and band transition of bound states in the continuum in leaky-mode photonic lattices
Sun-Goo Lee, Seong-Han Kim, Wook-Jae Lee
Bound states in the continuum (BICs) theoretically have the ability to confine electromagnetic waves in limited regions with infinite radiative quality () factors. However, in p…
Fourier-component engineering to control light diffraction beyond subwavelength limit
Sun-Goo Lee, Seong-Han Kim, Chul-Sik Kee
In conventional diffraction theory, a subwavelength period is considered a prerequisite to achieve interesting resonance-assisted physical phenomena, such as bound states in the co…
Band dynamics accompanied by bound states in the continuum at the third-order point in leaky-mode photonic lattices
Sun-Goo Lee, Seong-Han Kim, Chul-Sik Kee
Bound states in the continuum (BICs) and Fano resonances in planar photonic lattices, including metasurfaces and photonic crystal slabs, have been studied extensively in recent yea…
Anisotropic metallic metasurface superlattices supporting Fano resonances and bound states in the continuum
Sun-Goo Lee, Seong-Han Kim, Chul-Sik Kee
A perfect metal film with a periodic arrangement of cut-through slits, an anisotropic metallic metamaterial film, mimics a dielectric slab and supports guided electromagnetic waves…
Bound states in the continuum accompanied by avoided crossings in leaky-mode photonic lattices
Sun-Goo Lee, Seong-Han Kim, Chul-Sik Kee
When two nonorthogonal resonances are coupled to the same radiation channel, avoided crossing arises and a bound state in the continuum (BIC) appears in parametric space. This pape…
Metasurfaces with bound states in the continuum enabled by eliminating first Fourier harmonic component in lattice parameters
Sun-Goo Lee, Seong-Han Kim, Chul-Sik Kee
Conventional photonic lattices, such as metamaterials and photonic crystals, exhibit various interesting physical properties that are attributed to periodic modulations in lattice…
Band flips and bound-state transitions in leaky-mode photonic lattices
Sun-Goo Lee, Robert Magnusson
Leaky-mode photonic lattices exhibit intricate resonance effects originating in quasi-guided lateral Bloch modes. Key spectral properties are associated with phase-matched modes at…
