Pc. Teh et al., Phase encoding and decoding of short pulses at 10 Gb/s using superstructured fiber Bragg gratings, IEEE PHOTON, 13(2), 2001, pp. 154-156
A 7-chip, 160-Gchip/s phase-shift keyed code is assigned to short pulses af
ter reflection from a superstructured fiber Bragg grating. The code is then
recognized by a second grating, which is nominally identical to the encode
r grating. Such an encoding/decoding action is required in code-division mu
ltiple-access systems and packet-switched networks.
