I can remember a couple of paper describing the use of such delay lines to
compress laser pulses down to the femtoseconds domain.
IIRC I did google "delay line" +disperse or dispersive +chirp
I also saw mentionned the use of such lines in early radar technics but I
can't remember the purpose.

Sinewaves are time domain. Not spectra lines :-)
