    Title: Highly Charged Ion Modified Oxides (HCIMO) for Tunable 
Resistance.
    Abstract: Highly Charged Ion Modified Oxides (HCIMO) are achieved 
by irradiating a thin, high resistance oxide with highly charged ions 
(HCIs) and then depositing a conducting material of choice on top the 
irradiated oxide. The irradiation by HCIs preferentially ablates a 
region on the order of a cubic nanometer at each HCI's impact site 
breaking a hole through the ultra-thin oxide. This is demonstrated by 
preparing an insulating layer of aluminum oxide on a cobalt lower 
electrode layer, exposing the oxide to very dilute HCI radiation, and 
then depositing a cobalt upper layer. The data show a clear and 
systematic decrease in the resistance of the multilayer devices 
correlated to the HCI dose at very dilute doses. The nanometer 
dimensions of individual HCI impacts and the precise control over the 
dose combine to allow high precision selection of the material's 
resistance over a wide range of values, currently demonstrated over 
three orders of magnitude. As HCI modification only occurs within a few 
nanometers of the surface and generally does not affect metals, no 
special measures are needed to protect surrounding device structures 
from HCI damage. Since the size of the material modification is 
determined by the properties of a single ion, precise alignment is not 
required, only uniform illumination of the device area by the HCI beam, 
greatly simplifying commercial integration of HCI irradiation.

    Title: A Four-Wave Mixing Source of Squeezed Light for Image 
Processing and Interferometry
    Abstract: The invention provides a source of squeezed light, 
generated using a 4-level, four-wave mixing scheme in rubidium vapor. 
Strong relative-number squeezing between two beams has been 
demonstrated; much stronger than previously seen in any four-wave 
mixing system. The scheme relies on a chi(3) nonlinearity, and a 
single-pass, no-cavity, experimental implementation which has relaxed 
phase matching requirements, as compared to chi(2) crystal sources, and 
easily produces squeezing in multiple spatial modes.
