Investigation of Wide-FSR SOI Optical Filters Operating in C and L Bands [PDF]

open access: yesTelfor Journal, 2012
In this paper we present the investigation of optical filters based on triple ring resonator architectures in silicon-on-insulator technology. The generalized approach based on Mason’s rule and delay line signal processing has been implemented for ...

COMPREHENSIVE INVESTIGATION MODELING FOR SEMICONDUCTOR OPTICAL AMPLIFIER (SOA) [PDF]

open access: yesJordanian Journal of Computers and Information Technology, 2015
This paper presents the effects of the input signal on the gain and carrier density response of a semiconductor optical amplifier (SOA). The SOA is modeled using a segmentation method. The input bias current, input power, wavelength and the length of SOA

Density of optical degrees of freedom : intensity, linear and angular momentum [PDF]

open access: yes, 2014
For any optical system, optical eigenmodes describe solutions of Maxwells equations that are orthogonal to each other. In their simplest free space form, these modes correspond, for example, to Bessel, Laguerre-Gaussian or Hermite-Gaussian beams. However,

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
