Advanced Optical Materials, EarlyView.Chalcogenide phase change materials (PCMs) demonstrate a significant switchable volatile thermo‐optic response across visible and telecommunication bands. A broadband measurement is presented showing that some alloys exceed traditional reconfigurable materials in photonic integrated circuit (PIC) applications.

Advanced Photonics Research, EarlyView.In this study, the pronounced anisotropy in the optical properties of β‐Ga2O3 nanomembranes has been analized under a synchrotron nanoprobe. We have investigated the site‐specific contributions of distint Ga ions to the emission bands by combining polarization‐dependent X‐ray absorption near‐edge structure and X‐ray excited luminescence.

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

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 ...

Multicriteria analysis for behavioral segmentation
Journal of Telecommunications and Information Technology, 2004 Behavioral segmentation is a process of finding the groups of clients with similar behavioral patterns. The basic tool for segmentation is a clustering algorithm. However, the clusters generated by the algorithm depend on the preprocessing steps as well

Multispectral Polarization‐Insensitive Graphene/Silicon Guided Mode Resonance Active Metasurfaces
Advanced Photonics Research, EarlyView.CMOS‐compatible graphene/silicon active metasurfaces based on guided‐mode resonance filters are investigated. Simulations reveal a high extinction ratio (>25 dB), a narrow linewidth (≈1.5 nm), and polarization‐insensitive operation. Multispectral mid‐infrared performance is achieved via geometrical scaling.
