A theoretical/experimental research program was |
|
undertaken to settle the fundamental limits of all- |
|
optical regeneration, switching, and time recovery, with |
|
the aim of quantifying the optimal performance and |
|
evaluating how low the signal can be tolerated before |
|
amplification/regeneration is necessary. Towards this |
|
goal the contractor performed a quantum-mechanical |
|
analysis of a nonlinear interferometer that achieves |
|
optical switching via cross-phase modulation resulting |
|
from the Kerr effect. Northwestern showed how this device |
|
performs as a very precise optical regenerator, highly |
|
improving the transmitted bit-error rate in the presence |
|
of loss. On the experimental side, they made progress on |
|
an ongoing experiment to measure the quantum noise |
|
properties of a nonlinear-fiber Sagnac interferometer. A |
|
dual polarization scheme was devised to suppress the |
|
guided acoustic-wave Brillouin scattering in the fiber |
|
that hampers measurement of the quantum noise. Initial |
|
test showed good suppression of the classical noise |
|
resulting from guided acoustic-wave Brillouin scattering. |
