We demonstrate a simple platform for reconfigurable generation of arbitrary RF chirped waveforms from a single CW laser. Our scheme is capable of generating >100 GHz bandwidth chirps with a time-bandwidth product up to ∼1300.
We propose and demonstrate a new and extremely simple concept of reconfigurable photonic generation of arbitrary RF waveforms, based on a single CW laser and a frequency shifting loop. Our system does not require broadband light source or fast electronic generator. It is capable of generating arbitrary RF waveforms with duration ranging from 1 ns to more than 100 ns, and with dynamic performances...
We demonstrate a novel technique for the generation of fully-reconfigurable radio frequency chirped waveforms with extremely simple hardware based on a single CW laser and a frequency-shifting loop. All the waveform parameters, namely sign and value of the chirp rate, bandwidth, repetition rate and chirp duration are fully reconfigurable by simply tuning the frequency of a MHz-range single RF tone...
Optical frequency combs (OFCs) have led to an impressive number of achievements, including multi-heterodyne spectroscopy [1]. Mode-locked OFCs have been widely used due to their exceptional spectral bandwidth, but they usually require sophisticated locking methods to control the free spectral range (FSR) and the absolute frequency of the comb. A promising alternative is provided by electro-optic OFCs,...
Photonic generation of radio-frequency (RF) chirped signals has proven an attractive solution to overcome the limitations of conventional electronic waveform generators. However most of the designs proposed so far make use of a mode-locked laser as a broadband light source, resulting in high cost and complexity [1, 2]. Here we propose a much simpler concept of photonic generation of arbitrary RF chirped...
