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 ...

Advanced Optical Materials, EarlyView.2PP of photopolymers containing QDs is an advanced fabrication strategy for creating innovative devices at various scales. The development of reliable protocols for the homogeneous integration of QDs into photopolymers, along with precise control over the optical phenomena occurring during 2PP, enables the realization of structures ranging from 4D ...

Advanced Optical Materials, EarlyView.Here, recent progress is highlighted in colloidal magnetoplasmonic hybrid nanomaterials, with a focus on chiral plasmonics. Metal nanocrystals with intrinsic chiroptical features can lead to a combination of chiral plasmonics and magneto‐optics effects when interacting with the magnetic counterpart, offering a foundation for systematically designing ...

Telecommunications in Jericho [PDF]
SSRN Electronic Journal, 2002 This essay, written three years before the enactment of the Telecommunications Act of 1996, is a reminder of how little has been accomplished in deregulating telecommunications. In 1993, I erroneously predicted that American telecommunications regulation was about to collapse like the walls of Jericho.

Advanced Optical Materials, EarlyView.The excitation of a transition‐metal azo Schiff‐base complex with a 1064 nm laser induces a series of nonlinear optical effects. These effects include the second harmonic generation at 532 nm and third harmonic generation at 355 nm. This process demonstrates the potential of the complex for high‐order nonlinear optical applications. Abstract This paper

High‐Resolution Electron‐Beam Poling of X‐Cut Lithium Niobate Thin Films
Advanced Optical Materials, EarlyView.A new periodic poling technique using electron beams to create stable, high‐quality ferroelectric patterns is developed in x‐cut thin‐film lithium niobate (TFLN). The method works at room temperature with both standard and MgO‐doped materials, affords ferroelectric domain pitches as small as 375 nm, and lends itself to seamless integration with state ...

Spectrum Sharing Approach: Turkey Model Proposal
Revista de Direito, Estado e Telecomunicações[Purpose] Spectrum is a scarce and valuable national resource. With 5G, it is predicted that the demand for spectrum will increase gradually. In order to overcome the increasing data traffic problem and connection needs, the spectrum should be used as ...
