All-optical 2R logic regeneration is demonstrated using a vertical cavity semiconductor optical amplifier. The optical switching threshold is 1 µW, with 10 dB gain and >6:1 (8dB) extinction ratio. Performance limits are also discussed.
We model the non-linear gain characteristics of a Fabry-Perot semiconductor optical amplifier using a modified photon density rate equation. Good agreement is found with experimental results, with the simulation accurately reproducing all the major characteristics of the amplifier. To our knowledge, this is the first calculation using only the rate… (More)
