Abstract

We present a high-capacity ultrafast all-optical time demultiplexer that can be employed to retrieve 40 gigabits/second (Gb/s) base-rate channels from a 640Gbs single-polarized signal. The demultiplexer utilizes ultrafast effects of filtered chirp of a semiconductor optical amplifier. Excellent demultiplexing performance is shown at very low switching powers: +8dBm (640Gbs data) and 14dBm (40GHz clock). The demultiplexer has a simple structure and, in principle, allows monolithic integration.
