Optical Analog-to-Digital Conversion System Based on Compressive Sampling

A novel scheme of optical analog-to-digital conversion system is proposed based on compressive sampling and the recent electrical modulated wideband converter. The proposed optical solution is more stable and implementable in practice. Because of the ultranarrow optical pulseswidth, the proposed solution can provide a uniform signal-to-noise attenuate of all frequency bins, compared to its electrical counterpart.
