| Abstract: | The spatial coherence of lightwave extends the ability of optical information-processing systems based on the spatial parallelism. Orthogonally to space, the temporal coherence also raises their potential by make good use of the vast optical frequency domain, i.e., the frequency domain multiplexing. The frequency domain attracts neural network systems because many of the neural specific dynamics originate from the distributed and parallel architecture. Furthermore, the optical carrier frequency can become the key information for modulation of the network behavior such as learning, self-organization and adaptive processing. In this chapter, we treat the complex-valued neural networks from the viewpoint of frequency-sensitive coherent lightwave information processing. We describe the theory and experimental results where the carrier frequency is found useful to control the learning and processing behavior of the neural networks. | |
