Design and Demonstration of Apodized Comb Filters on SOI
IEEE Photonics Journal, 2012 We report on the design, modeling, and characterization of apodized comb filters in the silicon-on-insulator platform. These devices are based on sampled gratings, wherein the comb response is generated by a convolution of a regular grating by a ...

Cascaded Photonic Crystal Fiber Interferometers for Refractive Index Sensing
IEEE Photonics Journal, 2012 We present a cascaded fiber device based on photonic crystal fiber (PCF) interferometers for refractive index (RI) sensing. The PCF modal interferometers have microbubbles at both sides of the splice regions.

High Extinction Ratio Magneto-Optical Fiber Modulator Based on Nanoparticle Magnetic Fluids
IEEE Photonics Journal, 2012 A novel magneto-optical fiber modulator with a high extinction ratio (ER) based on a polarization interference structure is proposed. A magnetic fluid (MF) film and a section of a polarization-maintaining fiber (PMF) are inserted into the structure to ...

Finite-temperature reaction-rate formula: Finite volume system, detailed balance, $T \to 0$ limit, and cutting rules [PDF]
, 1997 A complete derivation, from first principles, of the reaction-rate formula for a generic process taking place in a heat bath of finite volume is given. It is shown that the formula involves no finite-volume correction.

All-Optical Sensing of the Components of the Internal Local Electric Field in Proteins
IEEE Photonics Journal, 2012 Here, we present a new all-optical method of interrogation of the internal electric field vector inside proteins. The method is based on experimental evaluation of the permanent dipole moment change upon excitation and the pure electronic transition ...

Harish-Chandra's volume formula via Weyl's Law and Euler-Maclaurin formula
, 2013 Harish-Chandra's volume formula shows that the volume of a flag manifold $G/T$, where the measure is induced by an invariant inner product on the Lie algebra of $G$, is determined up to a scalar by the algebraic properties of $G$.

A Slot-Based Surface Plasmon-Polariton Waveguide With Long-Range Propagation and Superconfinement
IEEE Photonics Journal, 2012 A full-vector spectral element method (SEM) is applied to model and simulate surface plasmon-polariton (SPP) waveguides. Gauss-Lobatto-Legendre (GLL) polynomials are used to construct higher-order basis functions to achieve spectral accuracy.
