We explore the nature and extent of these tradeoffs specific to each mechanism and identify the optimal operation modes for each.

• Abstract: High quality squeezed light is an important resource for a variety of applications. Multiple methods for generating squeezed light are known, having been demonstrated theoretically and experimentally. However, the effectiveness of these methods -- in particular, the inherent limitations to the signals that can be produced -- has received little consideration. Here we present a comparative theoretical analysis for generating a highly-displaced high-brightness squeezed light from a linear optical method -- a beam-splitter mixing a squeezed vacuum and a strong coherent state -- and parametric amplification methods including an optical parametric oscillator, an optical parametric amplifier, and a dissipative optomechanical squeezer seeded with coherent states. We show that the quality of highly-displaced high-brightness squeeze states that can be generated using these methods is limited on a fundamental level by the physical mechanism utilized; across all methods there are significant tradeoffs between brightness, squeezing, and overall uncertainty. We explore the nature and extent of these tradeoffs specific to each mechanism and identify the optimal operation modes for each, and provide an argument for why this type of tradeoff is unavoidable for parametric amplifier type squeezers.

  We propose how to achieve coherent manipulation and enhancement of quantum entanglement in a hybrid optomechanical system. The advantages of this system are twofold: (i) one can effectively regulate the light-mirror interactions by introducing a squeezed intracavity mode via the OPA; (ii) when properly matching the squeezing parameters between the squeezed cavity mode and the injected squeezed vacuum reservoir, the optical input noises can be suppressed completely.

  Brillouin-Mandelstam scattering is a three-wave mixing process between two optical fields and one acoustic field. We employ quantum optical techniques to characterize the second-order coherence of Stokes scattering across the Brillouin lasing threshold. Results demonstrate that applying second-order-coherence and photon-counting measurements to Brillouin scattering provides new methods to advance our understanding of Brillouin scattering.

  Weak squeezed vacuum light plays an important role in quantum storage and generation of various quantum sources. General homodyne detection (HD) cannot determine weak squeezing due to the low signal to noise ratio and the limited resolution of the HD system. This method can be used to measure other quantum features for various quantum states with extremely weak non-classicality.

  In conventional nonlinear media driven by femtosecond pulses, multiple dispersion orders limit the effective interaction length available for parametric amplification. Here, we use the dispersion engineering available in periodically poled thin-film lithium niobate nanowaveguides to eliminate several dispersion orders at once. The large peak intensity associated with a short pump pulse can provide gain to signal photons without undergoing pulse distortion or temporal walk-off.
