Generation of tunable continuous-wave microwave signals using photonic techniques
This paper reviews two photonic techniques which have been recently proposed and demonstrated by us for generating tunable continuous-wave microwave signals. In general, both techniques are based on the photonic processing ...
Photonic generation of frequency-tunable microwave signals using an array of uniformly spaced optical combs
We show analytically as well as experimentally a photonic technique for generation of frequency-tunable microwave signals. The technique involves propagating an array of uniformly spaced optical combs with identical comb ...
Linearization of an optically sampled analog-to-digital converter
In this paper, we show experimentally for the first time a 2 GSamples/s optically sampled analog-to-digital converter based on dual-output modulation and balanced photodetection scheme. Linearization in the form of arcsine ...
Photonic generation of tunable continuous-wave microwave signals using a temporally-stretched and chirped pulse-train
We show analytically and experimentally that direct photodetection of a temporally-stretched and chirped optical pulse-train together with its time-delayed replica can be exploited to realize the generation of tunable ...
Photonic generation of microwave pulses with wide frequency multiplication tuning range
In this paper, we propose an approach to generate microwave pulses with wide frequency multiplication tuning range based on the unbalanced temporal pulse shaping (TPS) principle. The key to achieving a wide tuning range ...
Frequency-tunable millimeter-wave generation technique based on spectral-filtering of a supercontinuum source
In this paper, we show analytically for the first time that spectral-filtering a supercontinuum source into equally-spaced optical combs with identical comb profile can lead to the generation of frequency-tunable microwave ...
