Accurate conversion of wideband multi-GHz analog signals into the digital domain has long
been a target of analog-to-digital converter (ADC) developers, driven by applications in …

Conversion of analog signals into digital signals is one of the most important functionalities
in modern signal processing systems. As the signal frequency increases beyond 10 GHz …

This paper reviews over 30 years of work on photonic analog-to-digital converters. The
review is limited to systems in which the input is a radio-frequency (RF) signal in the …

Digital‐to‐analog converters (DAC) are indispensable functional units in signal processing
instrumentation and wide‐band telecommunication links for both civil and military …

We demonstrate a method to compensate multi-channel mismatches that intrinsically exist in
a photonic analog-to-digital converter (ADC) system. This system, nominated time …

Real‐time wideband digitizers are the key building block in many systems including
oscilloscopes, signal intelligence, electronic warfare, and medical diagnostics systems …

Optically sampled analog-to-digital converters (ADCs) combine optical sampling with
electronic quantization to enhance the performance of electronic ADCs. In this paper, we …

We present theory and experiments for a microwave-to-digital photonic link capitalizing on
the linearity of optical phase modulation and coherent optical I/Q demodulation to achieve …

We utilized and characterized high-power, high-linearity modified unitraveling carrier
(MUTC) photodiodes for low-phase-noise photonic microwave generation based on optical …

Over the past ten years, DARPA has made significant investments toward advancing the
field of microwave photonics. This paper reviews DARPA-funded progress in this subject …
