Demonstration of 40 GHz Analog-to-Digital Conversion Using Copy-and-Sample-All Parametric Processing

Abstract

We present the result of an optical analog-to-digital conversion front-end based on the copy-and sample-all principle for the first time. The new architecture uses self-seeded multicasting and polychromatic sampling. Operation at 40 GHz and 6 ENOBs is experimentally demonstrated.
