Investigation of turbulence effect on the free space optical link for ground-to-train communications [PDF]
There is a growing demand for high mobility and ultrafast internet/data services which drives the motivation for free space optical (FSO) communications for high speed trains.

Controlling the Spatial Coherence of an Optical Source Using a Spatial Filter
This paper presents the theory for controlling the spectral degree of coherence via spatial filtering. Starting with a quasi-homogeneous partially coherent source, the cross-spectral density function of the field at the output of the spatial filter is ...

Transmission of a 25 Gbps non-return to zero signal over a hybrid link of 20 km standard single-mode fibre and 500 m free-space optics under weak-to-moderate turbulence regimes is demonstrated via simulation to provide a practical solution for the last ...

Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Metamaterial unipolar quantum optoelectronics for mid-infrared free-space optics
Free-space optical communications in the mid-infrared transparency windows (4–5 and 8–14 μm wavelength regions) is emerging as a viable solution for high bitrate data transmission.

An optically powered, free space optical communications receiver
Two of the key components of sensor motes are a power source and a communications receiver. One approach to creating very small motes is to use free space optical communication and to scavenge power from the optical downlink. In this paper photodiodes are described that were made on a standard CMOS process and generate electrical power from the ...

An embedded adaptive optics real time controller [PDF]
The design and realisation of a low cost, high speed control system for adaptive optics (AO) is presented. This control system is built around a field programmable gate array (FPGA).

Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
