A Poisson process P-lambda on R-d with causal structure inherited from the the usual Minkowski metric on R-d has a normalised discrete causal distance D-lambda (x, y) given by the height of the longest causal chain normalised by lambda(1/d)c(d). We prove t ...
Significant progress has been made in integrating novel materials into silicon photonic structures in order to extend the functionality of photonic circuits. One of these promising optical materials is BaTiO3 or barium titanate (BTO) that exhibits a very l ...
The present work concerns the approximation of the solution map S associated to the parametric Helmholtz boundary value problem, i.e., the map which associates to each (real) wavenumber belonging to a given interval of interest the corresponding solution o ...
Large-scale photonic switches are essential devices for energy-and cost-efficient optical communication networks in cloud and data-intensive computing. Silicon photonics is an attractive platform for high-density photonic integrated circuits with low manuf ...
Highly integrated optical circuit switch (OCS) with large port counts (~100x100) is achievable by combining silicon photonics and MEMS technologies. We will review the design trade-offs, performance scaling, and the current state of the art. ...
A novel photonic integrated circuit architecture for implementing orthogonal frequency division multiplexing by means of photonic generation of phase-correlated sub-carriers is proposed. The circuit can also be used for implementing complex modulation, fre ...
Introduced 50 years ago by David Kazhdan, Kazhdan's Property (T) has quickly become an active research area in mathematics, with a lot of important results. A few years later, this property has been generalized to discrete group actions by Robert J. Zimmer ...
Large-scale (50x50 and 64x64) integrated photonic switches have been realized by combining silicon photonics with efficient micro-electro-mechanical-system (MEMS) switching mechanisms. Low on-chip loss (0.058dB/port) and sub-microsecond switching time have ...
Integrated microresonators are essential building blocks of linear and nonlinear photonic devices. Here we show that the performance of high-Q silicon nitride microresonators for nonlinear photonics strongly depends on the ideality of their coupler design. ...
The formation of undesired high molecular weight species such as dimers is an important quality attribute for therapeutic monoclonal antibody formulations. Therefore, the thorough understanding of mAb dimerization and the detailed characterization mAb dime ...
