Electronics Letters, 2021 To realise an optical packet switching system, a tunable laser that can achieve high‐speed and wide‐range tuning is required. One candidate, we have studied for this role, is the tunable distributed amplification (TDA)‐distributed feedback (DFB) laser ...

Dynamic Wavelength Grouping for Quality of Service in Optical Packet Switching
IEEE Access, 2021 This paper concerns Quality of Service (QoS) provisioning in Optical Packet Switching (OPS) networks. We address the topic by proposing Dynamic Wavelength Grouping (DWG) for OPS, in this technique, available wavelengths are dynamically partitioned and ...

Dynamically reconfigurable optical packet switch (DROPS)
Optics Express, 2006 A novel Dynamically Reconfigurable Optical Packet Switch (DROPS) that combines both spectral and spatial switching capabilities is proposed and experimentally demonstrated for the first time. Compared with an Arrayed Waveguide Grating Router (AWGR), the added spatial switching capability provided by the microelectromechanical systems (MEMS) enables ...

FEBS Open Bio, EarlyView.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‐

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Quality of Service Aware Call Admission Control in Cell Based Multi-Service Photonic Network
Journal of Communications Software and Systems, 2010 The article tackles the problem of quality of service assurance in photonic networks. The idea of multi-servicephotonic network model with the coexistence of optical circuit and packet switching mechanisms and cell communication is used as a basis for ...

Petascale: A Scalable Buffer-Less All-Optical Network for Cloud Computing Data Center
IEEE Access, 2019 Optical packet switching is considered as a long-term solution for future data center networks due to their technological strengths, including high throughput, fine switching granularity, and excellent flexibility. However, most prior optical designs are
