Numerical analysis of four-wave mixing between 2 ps mode-locked laser pulses in a tensile-strained bulk SOA [PDF]
A numerical model of four-wave mixing between 2-ps pulses in a tensile-strained bulk semiconductor optical amplifier is presented. The model utilizes a modified Schrodinger equation to model the pulse propagation. The Schrodinger equation parameters such

Asymmetric optical loop mirror : analysis of an all-optical switch [PDF]
A general analytical framework for tetrahertz optical asymmetric demultiplexer (TOAD) switch operation is presented and compared with other switches that use a nonlinear optical element in a loop mirror.

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 ...

Sub-millijoule-level Fe:ZnSe chirped pulse amplifier seeded by KTA-based OPA system [PDF]
We developed a Fe:ZnSe chirped pulse amplifier with a KTA-based optical parametric amplifier, achieving 0.6 mJ pulses at 4-micron wavelength. It should be inherently carrier envelope phase stable and applicable to strong field science.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Novel design for noise controlled semiconductor optical amplifier [PDF]
The use of semiconductor optical amplifiers (SOA) in optical communications networks has so far been limited due to their inherent large noise figure (NF) compared to Erbium Doped Fibre Amplifiers.
