Abstract

We report an electro-optic directed optical decoder based on two cascaded microring resonators (MRRs). PN junctions embedded around the MRRs are employed to modulate the MRRs through the carrier-injection scheme. The optical decoding function from a 2-bit electrical signal to a 4-bit optical signal at the speed of 1 Gbps is performed successfully by the device.
