The demodulation of digital signals in a wireless system can be achieved either as coherent, in which the frequency and phase of the carrier have been previously recovered, or as non-coherent.

SCALINX, a fabless semiconductor company specializing in the design of system-on-chip (SoC) devices, was looking to develop a large, next-generation SoC integrating analog, digital, mixed-signal, and ...

In a finding that could have broad applications in optical devices, researchers have shown that they can transform incoherent light to almost fully coherent and vice versa. Brown University ...

Components of a typical laser include gain medium, laser pumping energy and resonant optical cavity. The output frequency of most lasers is fixed or within a small range, and it is difficult to ...

Fig 1. In this view of the architecture of an optical analyzer, the coherent reference receiver serves as the optical front end to the digitizer, taking as inputs two single-mode fibers, one carrying ...

This figure presents the results of distributed strain sensing over an approximately 100-m-long optical fiber utilizing BOCDR with periodic pseudo-random modulation. The top diagram illustrates the ...
