PHOTONIC RING-COUNTER USING BATCH-FABRICATED SYMMETRICAL SELF-ELECTRO-OPTIC-EFFECT DEVICES

We describe a photonic ring counter that demonstrates cascadability of batch-fabricated symmetric self-electroptic-effect devices at a bit rate of 12.5 Mbits/sec for conventional operation and at a bit rate of 50 Mbits/sec when the devices are operated as optical signal sense amplifiers. In each of these experiments the average laser power incident upon each device was less than 1 mW. The system switching speeds agree well with speeds calculated by using the measured switching energies of the devices.
