We report an electro-optic directed logic circuit which can implement the AND/NAND operations based on two parallel microring resonators. PIN diodes are embedded around microring resonators to achieve the carrier-injection modulation, two electrical pulse sequences regarded as the two operands of the operations are employed to modulate two microring resonators through the plasma dispersion effect. The operation results are obtained at the optical output ports in the form of light. Microheaters fabricated on the top of the microring resonators are employed to compensate two microring resonators resonance mismatch caused by the fabrication errors through the thermo-optic effect. The AND/NAND operations with the operation speed of 100Mbps are demonstrated simultaneously.
