S. Osawa et al., Arbitrarily-shaped optical pulse train synthesis using weight/phase-programmable 32-tapped delay line waveguide filter, ELECTR LETT, 37(22), 2001, pp. 1356-1357
Generation of optical pulse train of arbitrary waveform based upon Fourier
spectrum synthesis is experimentally demonstrated using a weight/phase-prog
rammable 32-tapped delay line waveguide filter along With a frequency-tunab
le fibre-optic comb generator.
