- Abstract: A novel planar configuration of a multi-port
encoder/decoder (E/D) is presented that has enhanced
performance in terms of beat-noise suppression and network
confidentiality. We insert a splitter and a set of phase shifters in
front of a standard arrayed waveguide grating (AWG)-based
multi-port E/D, to generate spectral-phase codes. The new
configuration keeps the same key features and it is able to
generate/process a set of different codes simultaneously; at the
same time, the network confidentiality is enhanced, because
only the intended receiver, which knows the phase shifter
values, is able to recognize the code. Furthermore, whereas the
auto-correlation function of the previous E/D has a triangular
shape, in this case it is similar to the input pulse, enhancing the
system cascadability and reducing the beat-noise.
