Abstract
A 40 GHz clock with low jitter is recovered from a 640 Gbit/s optical
time-division multiplexed (OTDM), single-polarised, return-to-zero
PRBS data signal. The clock recovery circuit is an injection-locked
loop which contains a 40 GHz Gunn oscillator, a 40 GHz pulse
source, and a semiconductor optical amplifier (SOA) assisted by a
filtered chirp as optical phase comparator.
