Lowering the Cross Correlation between Different Shape Parameters of the Inverse Grating Problem in Coherent Fourier Scatterometry
Angular Fourier Scatterometry techniques to solve inverse-grating problems have been widely used in semiconductor metrology since the initial work by den Boef et al. [1] because it is simple, fast and robust a...

Extension of the classical Fabry–Perot formula to 1D multilayered structures
In any field theory the interaction of a wave packet with a multilayered potential is of high theoretical and practical relevance. In the present work we show an extension to any number of layers of the classi...

Open AccessPerformance analysis of coherent optical scatterometry
Scatterometry is a well established technique currently utilized in research, as well as in industrial applications, to retrieve the properties of a given scatterer (the target) by looking at how the light com...

Optical Tomography of a Highly Squeezed, Continuous-Wave Vacuum-State
The Wigner distribution provides complete information about a given quantum state.[1] In quantum optics, it has been suggested [2] and demonstrated [3] that it is possible to determine experimentally the quant...

Realization of the Einstein-Podolsky-Rosen paradox for continuous variables in nondegenerate parametric amplification
The Einstein-Podolsky-Rosen (EPR) paradox is demonstrated experimentally for continuous variables by employing a nondegenerate optical parametric amplifier (NOPA). Such a system is analogous to and under some ...

Squeezed State Generation and Nonclassical Correlations in Nondegenerate Parametric Down Conversion
We report observations of squeezed state generation in a subthreshold optical parametric oscillator (OPO) operated in a frequency degenerate but polarization nondegenerate mode. Reductions in photocurrent fluc...
