Abstract :
In photonic label routing networks, recognition of optical labels is one of the key functions. We have proposed waveguide-type optical circuits for recognition of optical labels encoded in quadri-phase-shift-keying (QPSK) form. We discuss contrast ratio in the label recognition outputs and its degradation due to additive noise was discussed.
