Abstract

We present our work on fully integrated hybrid silicon optical buffers capable of holding 40 byte packets at 40 Gb/s. These devices consist of low loss silicon waveguides and cascaded amplifiers to overcome passive losses in a 1.1 m long delay line. Since cascading multiple gain elements leads to ASE (noise) accumulation, reshaping elements in the form of saturable absorbers are integrated in the delay. Noise filtering in the buffer is investigated by simulating the eye diagram for a delay line with 1R regenerators and comparing it to that of a 2R regenerator. Finally, preliminary experimental data from the optical buffer is shown.
