A new amplifying technique for weak and noisy optical signals

FONEX is proud to be working in collaboration with l’Institut National de la Recherche Scientifique. With the help of Ph. D. student Benjamin Crockett and colleagues, they are discovering new techniques that recover the weak noise-dominated optical signals.

This new method allows for researchers to use passive amplification of the signal of interest over noise giving access to signals that would not be recovered otherwise. This technique increase the energy of the signal of interest while reducing its relative noice content. To accomplish this new technique Benjamin and his colleagues must look at the Talbot self-imaging effect, when looked at is a periodic train of pulses that propagates through a dispersive medium such as an optical fiber. It provides frequent components of light to travel at different speeds.
