Methods and apparatus for photonic arbitrary waveform generation over wide-bandwidth and extended time apertures

A method and apparatus for producing an arbitrary broadband waveform includes generating a first narrowband waveform and generating a frequency-shifted replica by frequency shifting the first narrowband waveform by a frequency shift. A second narrowband waveform is also generated. A broadband wavefo...

Beschreibung
Zusammenfassung:	A method and apparatus for producing an arbitrary broadband waveform includes generating a first narrowband waveform and generating a frequency-shifted replica by frequency shifting the first narrowband waveform by a frequency shift. A second narrowband waveform is also generated. A broadband waveform is generated by combining the frequency-shifted replica and the second narrowband waveform.
