Noise analysis of polarization-based optoelectronic connectionist machines
Abstract:
Adaptive optical systems such as the bipolar, polarization-based optical connectionist machine are capable of operating in the presence of substantial noise generated by optoelectronic devices such as spatial light modulators, sources, and detectors. We present results on two optoelectronic connectionist machines that implement the single-layer delta rule and backward error propagation neural network algorithms and analyze the influence of noise on their performance. Results show that an optoelectronic neural network with 200 input units can easily classify 30 random patterns with a spatial light modulator contrast ratio of 10:1 and output cross talk of 10%.

Biasing of P-N Junction
In equilibrium, no external voltage is applied across the p-n junction. The depletion region is formed at the junction interface due to the diffusion of carriers, which leaves behind charged dopants, acceptors on the p-side, and donors on the n-side. These immobile charges create an electric field that prevents further diffusion of carriers. The related energy band...

Pole and System Stability
Simple poles are unique roots of the denominator polynomial. Each simple pole corresponds to a distinct solution to the system's characteristic equation, typically resulting in exponential decay terms in the system's response.
