Noise performance of a white light optical signal processor:part I-temporally partial coherent illumination
The effect on noise performance of a white-light optical signal processor under temporally partial coherent illumination is presented. The output signal-to-noise ratio (SNE) is evaluated through the well-known partial coherence theory. This output SNE is used as a means of measurement for the noise performance of the proposed white-light processing system. The sources of noise considered are the grain-noise and the phase-noise at the input and Fourier plane. Except For the grain-noise at the input plane, we show that the output SNR can be improved considerably by using a broadband temporally partial coherent illnminatioii.
