Complex modes in optical fibers and silicon waveguides
Nan Zhang, Ya Yan Lu
At a fixed frequency, a general wave field in an open optical waveguide is a sum of finite number of guided modes and an integral of radiation modes. Most studies on open lossless…
Parametric dependence of bound states in the continuum in periodic structures: vectorial cases
Lijun Yuan, Ya Yan Lu
A periodic structure sandwiched between two homogeneous media can support bound states in the continuum (BICs) that are valuable for many applications. It is known that generic BIC…
Circularly polarized states and propagating bound states in the continuum in a periodic array of cylinders
Amgad Abdrabou, Ya Yan Lu
Bound states in the continuum (BICs) in a periodic structure sandwiched between two homogeneous media have interesting properties and useful applications in photonics. The topologi…
Complex modes in an open lossless periodic waveguide
Amgad Abdrabou, Ya Yan Lu
Guided modes of an open periodic waveguide, with a periodicity in the main propagation direction, are Bloch modes confined around the waveguide core with no radiation loss in the t…
Exceptional points of Bloch eigenmodes on a dielectric slab with a periodic array of cylinders
Amgad Abdrabou, Ya Yan Lu
Eigenvalue problems for electromagnetic resonant states on open dielectric structures are non-Hermitian and may have exceptional points (EPs) at which two or more eigenfrequencies…
Resonant field enhancement near bound states in the continuum on periodic structures
Zhen Hu, Lijun Yuan, Ya Yan Lu
On periodic structures sandwiched between two homogeneous media, a bound state in the continuum (BIC) is a guided Bloch mode with a frequency within the radiation continuum. BICs a…
