Abstract
The potential performance of a hybrid analog-digital converter (ADC) is characterized for directly digitizing analog signals with frequencies as high as 18 GHz. The operation of the hybrid ADC is based on a time-division or wavelength-division multiplexing converter using highly chirped broadband pulses. An optical pulse, linearly chirped to fill the interpulse period, forms a quasi-continuous optical carrier. The chirped nature of the optical carrier creates a direct correspondence between time and wavelength within each pulse period. Subsequently, a wideband optical modulator is used to amplitude modulate the carrier with the input signal. The carrier is then wavelength-multiplexed into parallel channels.
