Abstract:

The main goal of our research is the achievement of substantial squeezing of the vacuum fluctuations associated with a soliton. If the soliton is injected into the probe port of a Mach-Zehnder interferometer and the squeezed vacuum is injected into the vacuum port, sub-shot noise measurements of the phase difference between the two arms of the interferometer can be performed. The soliton squeezing is being done in a Sagnac loop. This objective calls for a The development of pulse sources of 16Hz or higher rep-rate to combat Guided Acoustic Wave Brillouin Scattering b Development of an amplifier that brings the pulses to the energy level required for subpicosecond soliton propagation in the fiber loop c An understanding of the noise of the pump and d Demonstration of squeezing. All four of these objectives have been accomplished as shown in detail in the report. The first three accomplishments have the potential to affect source development for optical communications. The squeezing obtained is the best yet demonstrated by anyone. We expect further improvements with proper refinements of the system.
