Nonlocal response in plasmonic waveguiding with extreme light confinement
Nanophotonics, 2013 We present a novel wave equation for linearized plasmonic response, obtained by combining the coupled real-space differential equations for the electric field and current density.

A Directly-Written Monolithic Waveguide-Laser Incorporating a DFB Waveguide-Bragg Grating [PDF]
, 2008 We report the fabrication and performance of the first C-band directly-written monolithic waveguide-laser. The waveguide-laser device was created in an Erbium and Ytterbium doped phosphate glass host and consisted of an optical waveguide that included a distributed feedback Bragg grating structure.

Quantum waveguides with corners [PDF]
ESAIM: Proceedings, 2012 The simplest modeling of planar quantum waveguides is the Dirichlet eigenproblem for the Laplace operator in unbounded open sets which are uniformly thin in one direction. Here we consider V-shaped guides. Their spectral properties depend essentially on a sole parameter, the opening of the V.

A Rigorous Circuit Model for Simulation of Large-Scale Photonic Integrated Circuits
IEEE Photonics Journal, 2012 A rigorous circuit model for the simulation of large-scale photonic integrated circuit (PIC) is proposed and validated. Different from the conventional circuit theory, both guided and radiation fields are taken into consideration in the circuit model.

New silicon photonics integration platform enabled by novel micron-scale bends
, 2013 Even though submicron silicon waveguides have been proposed for dense integration of photonic devices, to date the lightwave circuits on the market mainly rely on waveguides with micron-scale core dimensions.
