Slice-Less Optical Arbitrary Waveform Measurement (OAWM) in a Bandwidth of More Than 600 GHz

We demonstrate an optical arbitrary waveform measurement (OAWM) technique that exploits optical frequency combs as multi-wavelength local oscillators (LO) and that does not require any optical slicing filters. In a proof-of-concept experiment, we achieve record-high bandwidths exceeding 600 GHz.
