Abstract: Here we present an atomic spiral diffractive element for the focusing, reflection, and directional scattering of light. We demonstrate how such a system imprints an angular momentum in its ...

Abstract: This paper presents a coding approach for achieving omnidirectional transmission of certain common signals in massive multi-input multi-output (MIMO) networks such that the received power at ...

Arrays for 'slow and wide' interconnections enable power-efficient and compact short reach links Coherent has announced what is claims is a breakthrough in short-reach optical interconnect technology ...
