Abstract

An interesting method for broadband arbitrary waveform generation is based on frequency upshifting of a narrowband microwave signal. In this technique, the original microwave signal is imaged into a temporally compressed replica using a simple and practical fiber-based system. Recently, it has been shown that the conventional limitations of this approach (e.g. bandwidth limitations) can be overcome by exploiting a temporal self-imaging (Talbot) effect in fiber. This effect can be used whenever the signal to be imaged is a quasi-periodic waveform (e.g. microwave tones or any arbitrary periodic waveform). This work provides a comprehensive review of the microwave frequency upshifting technique for broadband arbitrary waveform generation, with a special focus on the Talbot-based approach. The design specifications, and the associated practical capabilities and constraints, of fiber-based microwave frequency upshifting systems will be examined. The influence of higher-order effects, in particular second-order dispersion terms in the employed fibers, on the system performance will be evaluated and some additional design rules to minimize the associated detrimental effects will be given. Experimental evidence of our findings has been also provided. Our results show that microwave frequencies up to a few hundreds of GHz over nanosecond temporal windows can be easily obtained with the described technique using readily available (sub-)picosecond pulsed optical sources.
