Keeping the packet sequence in optical packet-switched networks

Optical Switching and Networking, 2005
This paper deals with optical packet switches with limited buffer capabilities, subject to asynchronous, variable-length packets and connection-oriented operation. The focus is put on buffer scheduling policies and queuing performance evaluation. In particular a combined use of the wavelength and time domain is exploited in order to obtain contention ...

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Time-Sliced Flexible Resource Allocation for Optical Low Earth Orbit Satellite Networks

IEEE Access, 2019
In future optical satellite networks with various service requirements, the bandwidth of a single traffic request occupies part of an inter-satellite link (ISL) channel capacity, thus leading to a greater demand for flexible resource allocation.

Organic Electrochemical Transistor Channel Materials: Copolymerization Versus Physical Mixing of Glycolated and Alkoxylated Polymers

Advanced Functional Materials, EarlyView.
This work discusses the use of blended channel materials in OECTs. It explores how mixing glycolated and alkoxylated polymers in various ratios offers a simpler and more efficient route to tuning OECT properties. The performance of the polymer blends is compared to the corresponding copolymers, demonstrating similar OECT characteristics, swelling ...

Complimentary code keying of spectral amplitude coding signals in optical buffering with increased capacity

Journal of the European Optical Society-Rapid Publications, 2020
Signal buffering services such as contention resolution and congestion avoidance are essential in optical packet switching networks. In this paper, an optical memory scheme based on spectral amplitude coding (SAC) and complementary code keying (CCK) is ...

Ultra-fast photonic packet switching with optical control [PDF]

Optics Express, 1997
We report the first demonstration of all-optical multi-bit address recognition at 250 Gb/s using a self-routing scheme. With bit period being only 4 ps, two address bits from each packet header were used for routing. Photonic packets can be removed(dropped) by a routing switch from network traffic at their destination.
