Demonstration of a Graphene Adjustable‐Barriers Phototransistor with Tunable Ultra‐High Responsivity
Advanced Optical Materials, EarlyView.A novel graphene‐based phototransistor with a tunable ultra‐high responsivity of 1.7 x 107 AW−1 has been demonstrated. Due to the selected material combination of amorphous silicon, graphene and n‐germanium, the device is potentially capable of dual‐band detection in the VIS‐IR range.

Towards Hardware implementation of video applications in new telecommunications devices [PDF]
Journal of Telecommunications, Volume 2, Issue 1, p75-85, April
2010, 2010 Among the areas, most demanding in terms of calculation is the telecommunication and video applications are now included in several telecommunication devices such as set-top boxes, mobile phones. Embedded videos applications in new generations of telecommunication devices need a processing capacity that can not be achieved by the conventional processor,

Institutions, Telecommunications Dynamics and Policy Challenges: Theory and Empirical Analysis for Germany [PDF]
The telecommunications sector was liberalized in the US and the EU in 1984 and 1998, respectively. In EU countries, price cap regulation has shaped this sector in a pro-competitive way that - with telecommunications obviously being a key element of the ...

A way of integrating deaf, hearing- and speech-impaired people into modern communication society
Journal of Telecommunications and Information Technology, 2006 This article deals with the exclusion of deaf, hearing- and speech-impaired people from our modern communication society, as they are unable to use the phone. This situation leads to discrimination and disadvantages in their everyday lives. One solution

Common Metrics for Analyzing, Developing and Managing Telecommunication Networks [PDF]
arXiv, 2017 The metrics play increasingly fundamental role in the design, development, deployment and operation of telecommunication systems. Despite their importance, the studies of metrics are usually limited to a narrow area or a well-defined objective. Our study aims to more broadly survey the metrics that are commonly used for analyzing, developing and ...

Advanced Photonics Research, EarlyView.This work demonstrates the use of reactive laser annealing to selectively tune the epsilon‐near‐zero condition of tin‐doped indium oxide patches integrated in silicon waveguides. This postgrowth annealing technique enables flexible control over the optical constants of transparent conducting oxides (TCOs) at critical telecom wavelengths, paving the way
