Abstract :
An all optical Viterbi decoder on a silicon chip was designed. The device is composed of an optical memory cell and two interfering input arms that use QPSK modulation to encode the incoming bits. The device has a shape of a ring resonator with a size of just a few micrometers and relies on the coupling of modes. Data processing of a few picoseconds is within the ability of the device.
