An improved argument principle root-search method for modes of slab waveguides, optical fibers, and spheres
S. Rao, P. Y. Chen, T. Grossinger +1
We update our root-search method for transcendental equations. Our method is globally convergent and is guaranteed to locate all complex roots within a specified search domain, sin…
Optimization of second-harmonic generation from touching plasmonic wires
Shimon Elkabetz, K. Nireekshan Reddy, Parry Y. Chen +2
We employ transformation optics to optimize the generic nonlinear wave interaction of second-harmonic generation from a pair of touching metallic wires. We demonstrate a 10 orders…
Resolving the Gibbs phenomenon via a discontinuous basis in a mode solver for open optical systems
Parry Y Chen, Yonatan Sivan
Partial differential equations are frequently solved using a global basis, such as the Fourier series, due to excellent convergence. However, convergence becomes impaired when disc…
An efficient solver for the generalized normal modes of non-uniform open optical resonators
Parry Y. Chen, Yonatan Sivan, Egor A. Muljarov
Modal expansion is an attractive technique for solving electromagnetic scattering problems. With the one set of resonator modes, calculated once and for all, any configuration of n…
Overcoming the bottleneck for quantum computations of complex nanophotonic structures: Purcell and FRET calculations using a rigorous mode hybridization method
Gilles Rosolen, Parry Yu Chen, Bjorn Maes +1
A calculation of the photonic Green's tensor of a structure is at the heart of many photonic problems, but for non-trivial nanostructures, it is typically a prohibitively time-cons…

K. Nireekshan Reddy, Parry Y. Chen, Antonio I. Fernández-Domínguez +1
We study surface second-harmonic generation (SHG) from a singular plasmonic structure consisting of touching metallic wires. We use the technique of transformation optics and relat…
Decoupling the energy and momentum of photons in the quasistatic limit
M J A Smith, P Y Chen
We theoretically show that the frequency and momentum of a photon are not necessarily proportional to one another at low frequencies in photonic crystals comprising materials with…
Generalizing normal mode expansion of electromagnetic Green's tensor to lossy resonators in open systems
Parry Y. Chen, David J. Bergman, Yonatan Sivan
We generalize normal mode expansion of Green's tensor to lossy resonators in open systems, resolving a longstanding open challenge. We obtain a simp…
Revisiting the boundary conditions for second-harmonic generation at metal-dielectric interfaces
K. Nireekshan Reddy, Parry Y. Chen, Antonio I. Fernández-Domínguez +1
We study second-harmonic generation (SHG) arising from surface nonlinearity at a metal-dielectric interface using a spectral decomposition method. Since our method avoids the need…
Spectral decomposition of the Lippmann-Schwinger equation applied to cylinders
Parry Y. Chen, David J. Bergman, Yonatan Sivan
We derive the spectral decomposition of the Lippmann-Schwinger equation for electrodynamics, obtaining the fields as a sum of eigenmodes. The method is applied to cylindrical geome…
Robust Location of Optical Fiber Modes via the Argument Principle Method
Parry Y. Chen, Yonatan Sivan
We implement a robust, globally convergent root search method for transcendental equations guaranteed to locate all complex roots within a specified search domain, based on Cauchy'…
Evaluation and regularization of generalized Eisenstein series and application to 2D cylindrical harmonic sums
Parry Y. Chen, Michael J. A. Smith, Ross C. McPhedran
In the study of periodic media, conditionally convergent series are frequently encountered and their regularization is crucial for applications. We derive an identity that regulari…
Reinterpreting the magnetoelectric coupling of polarizability tensors of infinite cylinders using symmetry: a simple TM/TE view
Parry Y. Chen, Jacob Ben-Yakar, Yonatan Sivan
Recently, Strickland et al retrieved dynamic polarizabilities of infinitely long wires at oblique incidence, reporting non-zero magnetoelectric coupling, seemingly defying existing…
