Paper Abstract

In this paper, a novel approach for loadable and erasable optical memory unit based on dual microring optical integrators coupled via 3×3 couplers is proposed and studied. The optical integrator, which can generate an optical step function for data storing, is synthesized using active media for loss compensation and a tunable phase shifter for data reading at any time. The input data into the memory is return-to-zero (RZ) signal, and the output data read out from the memory is also RZ format with a narrower pulse width, which is determined by the phase shift pulse. A great number of such memory units is promised to be densely integrated on a photonic circuit for future large scale data storage and buffer.
