Abstract: All-optical gate control signal generation is demonstrated
from flag pulses, using a Fabry–;P{\'e}rot filter followed by
a semiconductor optical amplifier. Ten control pulses are generated
from a single flag pulse having less than 0.45-dB amplitude
modulation. By doubling or tripling the number of flag pulses, the
number of control pulses increases approximately by a factor of
two or three. The circuit can control the switching state of all-optical
switches, on a packet-by-packet basis, and can be used for
nontrivial network functionalities such us self-routing.
Abstract: We present methods for obtaining high-repetition-
rate full duty-cycle RZ optical pulse trains from lower rate
laser sources. These methods exploit the memory properties of the
Fabry–;Perot filter for rate multiplication, while amplitude equalization
in the output pulse train is achieved with a semiconductor
optical amplifier or with a second transit through the Fabry–;Perot
filter.We apply these concepts to experimentally demonstrate rate
quadruplication from 10 to 40 GHz and discuss the possibility of
taking advantage of the proposed methods to achieve repetition
rates up to 160 GHz.
