Abstract
A high dynamic range narrow-band optical analog-to-digital converter configuration is proposed and demonstrated in which a narrow-band electrical input signal is converted to a baseband digitized signal while suppressing second-order modulator distortion products. Operation is demonstrated at 439 MHz, resulting in 72 dB of intermodulation suppression for a 0.8-ms sampling time.
