Telecommunications and competitiveness
Réseaux. The French journal of communication, 1994 Summary: When the relationship between the development of corporate telecommunications and competitiveness is considered, a number of terminological ambiguities should first be clarified. Three situations can then be defined and examined, according to whether telecommunications are considered as having a neutral, passive, or active role. The capacities

Advanced Optical Materials, EarlyView.Curcuminoid boron difluoride dyes containing triphenylamine units are prepared and their photophysical and electrochemical properties are investigated. These new light‐emitting dyes are used in organic light‐emitting diodes (OLEDs) emitting at 800 nm with 1% external quantum efficiency, and show low threshold amplified spontaneous emission in thin ...

Telecommunications at the crossroads in India
IIMB Management Review, 2015 AbstractThe telecommunications sector is going through an interesting phase in its evolution. Cellular mobile service providers have been at the root of the massive expansion in the number of subscribers and usage. Since last year the pace of growth has slowed down and it is increasingly clear that revenues from voice services alone will not be ...

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.

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
