E. Park et al., SIMULTANEOUS ALL-OPTICAL PACKET-HEADER REPLACEMENT AND WAVELENGTH SHIFTING FOR A DYNAMICALLY-RECONFIGURABLE WDM NETWORK, IEEE photonics technology letters, 7(7), 1995, pp. 810-812
We experimentally demonstrate a method of simultaneous all-optical hea
der replacement and wavelength shifting, These functions, important in
a dynamically-reconfigurable WDM network, are realized by using cross
-gain compression in a semiconductor optical amplifier, and by using t
hree-level modulation of a probe laser only when We header bits requir
e changing, We simultaneously replace the 8-bit header of a 1-Gb/s pac
ket and wavelength-shift the entire packet by 19 nm, A receiver sensit
ivity of -27 dBm at 10(-9) BER is measured when using a 416-bit NRZ da
ta packet Our approach requires no guard bits and allows both the head
er and data to be at the same bit rate and wavelength.
