An all-optical serial header processor is demonstrated using a semiconducto
r laser amplifier in a loop mirror configuration (SLALOM). The operation of
the header processor is discussed and it is experimentally demonstrated wi
th a 10Gbit/s Manchester encoded (information rate of 5Gbit/s) packet strea
m. The operation of the header processor is based on the correlation functi
on of the SLALOM. The header processor can be utilised in devising all-opti
cal packet switches.
