ON THE PHYSICAL ORIGIN OF THE 3-DB NOISE FIGURE LIMIT IN LASER AND PARAMETRIC OPTICAL AMPLIFIERS

  • Desurvire E.

We integrate into a unifed model the fundamental conclusions of previous theoretical works concerning the quantum theory of linear optical amplifiers. We analyze the statistical processes contributing to noise in both laser and parametric amplification. We show that the so-called “signal/amplified spontaneous emission” beat noise directly originates from thermal statistics ...

ARCHITECTURE AND PERFORMANCE OF A BROADCAST AND SELECT PHOTONIC SWITCH

  • Chiaroni D.
  • Masetti F.
  • Sotom M.

A new photonic packet switch based on wavelength encoding of information and on the broadcast-and-select principle for routing is presented. A suitable management of a set of fiber delay lines to allow all-optical output queuing is performed through electronic control. Implementation and traffic aspects are analyzed. Experimental results are given ...
