Dispersion-designed structural geometry enables group-velocity mismatch of interacting lights to be smoothed to zero, for wide-range frequency conversion. Advancements in quantum information ...

Photons have an important role for transmitting a quantum state among distantly located physical systems, such as atoms, ions and solid-state systems 1,2,3,4, which are used as memories and/or ...

As high-speed analog-to-digital converter (ADC) technology improves, so does the need to resolve very high intermediate frequencies (IFs) accurately at high speeds. This poses two challenges: the ...

A software-defined radio (SDR) uses a general-purpose computer processor to perform aspects of digital signal processing in place of analog circuit hardware. This allows for greater flexibility in ...

Operators of telecommunication satellites want to be able to offer their customers flexible data and broadcast services anywhere in the world, anytime. Rapidly changing global events like breaking ...
