A distributed-feedback (DFB) laser with a carved waveguide in the active region integrated with an electroabsorption modulator is studied experimentally and theoretically.

We analyze wavelength tunable, electro-optic polarization conversion in a birefringent waveguide accomplished with a multiple cascade of alternating TE-->TM mode converter and TE/TM phase shifte

In this paper, we design wavelet domain features allowing to test texture replicability.

We build compactly supported biorthogonal wavelets and perfect reconstruction filter banks for any lattice in any dimension with any number of primal and dual vanishing moments.

A new nonlinear image filtering technique for multiplicative noise in the wavelet transform domain is presented.

Several studies have demonstrated the effectiveness of the wavelet decomposition as a tool for reducing large amounts of data down to compact wavelet synopses that can be used to obtain fast, accur

In this paper, we introduce Probabilistic Wavelet Synopses, the first wavelet-based data reduction technique with guarantees on the accuracy of individual approximate answers.

(Title was originally Wavelet Thresholding via MDL: Simultaneous Denoising and Compression) In the context of wavelet denoising and compression, we study minimum description length (MDL) criteria f

In this article, we review techniques for building and analyzing wavelets on irregular point sets in one and two dimensions. We discuss current results both on the practical and theoretical side.

Waves in Electron Streams and Circuits Of recent years, a good deal of work has appeared concerning small linear perturbations of uniform clouds of electrons and ions.* A number of questions can be
