H. Tsuda et al., Spectral encoding and decoding of 10Gbit/s femtosecond pulses using high resolution arrayed-waveguide grating, ELECTR LETT, 35(14), 1999, pp. 1186-1188
A 10Gbit/s, 810fs, return-to-zero signal is spectrally encoded, transmitted
over a 40km dispersion shifted fibre, and decoded using a photonic spectra
l encoder and decoder pair that uses high resolution arrayed-waveguide grat
ings and phase filters. A 255 bit binary phase code with the maximum length
sequence is used for spectral coding.
