In this approach, the input signal is first sampled at a rate higher than that required by the Nyquist criterion and then presented spatially as the input to a two-dimensional error diffusion neural network consisting of M/spl times/N neurons, each representing a pixel in the image space. The neural network processes the input oversampled analog image and produces an M/spl times/N pixel binary or halftoned output image. By design of the neural network, this halftoned output image is an optimum representation of the input analog signal. Upon convergence, the neural network minimizes an energy function representing the frequency-weighted squared error between the input analog image and the output halftoned image. Decimation and low-pass filtering techniques digitally sum and average the M/spl times/N pixel output binary image using high-speed digital electronic circuitry. By employing a two-dimensional smart pixel neural approach to oversampling ADC, each pixel constitutes a simple oversampling modulator thereby producing a distributed A/D architecture. Spectral noise shaping across the array diffuses quantization error thereby improving overall SNR performance. Each quantizer within the network is embedded in a fully-connected distributed mesh feedback loop which spectrally shapes the overall quantization noise thereby significantly reducing the effects of component mismatch typically associated with parallel or channelized A/D approaches.","PeriodicalId":415720,"journal":{"name":"2000 Digest of the LEOS Summer Topical Meetings.

The strong polarization sensitivity of the mixing process is, however, a major issue in the utilization of the FWM technique in practical networks. Several schemes for polarization insensitive FWM in SOAs have been demonstrated, which utilise rather complex configurations involving several optical components. Recently, we proposed an extremely simple scheme for polarization insensitive FWM, utilizing just one polarization insensitive SOA and one pump wave. Furthermore, employing two pump sources in the scheme, polarization insensitive and frequency-conversion frequency-interval independent FWM can be also obtained. In all the aforementioned configurations, polarization insensitive SOAs were employed to achieve the polarization insensitive FWM performance. In this paper, we will show that polarization insensitive FWM operation can also be realised, using a polarization sensitive SOA by modifying the configuration","PeriodicalId":415720,"journal":{"name":"2000 Digest of the LEOS Summer Topical Meetings.

In this work, we report on the use of spectroscopic ellipsometry for monitoring and control of AlGaAs growth in molecular beam epitaxy. Knowledge of the optical constants as a function of composition and growth parameters is essential for modeling to be able to extract the composition and growth rate from measured SE data. For this work, we have used the virtual interface approximation to extract the growth rate and composition of of Al/sub x/Ga/sub 1-x/As films grown at normal and elevated temperatures. At elevated temperatures, Ga possessed a sticking coefficient less than 1. 900 K Ga was observed to grow at a constant rate. At elevated temperatures the Ga growth rate decreased until at 940 K no continued growth was observed. Under all conditions SE accurately predicted the observed growth rates.","PeriodicalId":415720,"journal":{"name":"2000 Digest of the LEOS Summer Topical Meetings. Electronic-Enhanced Optics.
