C. Joergensen et al., ALL-OPTICAL WAVELENGTH CONVERSION AT BIT RATES ABOVE 10 GB S USING SEMICONDUCTOR OPTICAL AMPLIFIERS/, IEEE journal of selected topics in quantum electronics, 3(5), 1997, pp. 1168-1180
This work assesses the prospects for high-speed all-optical wavelength
conversion using the simple optical interaction with the gain in semi
conductor optical amplifiers (SOA's) via the interband carrier recombi
nation, Operation and design guidelines for conversion speeds above 10
Gb/s are described and the various tradeoffs are discussed. Experimen
ts at bit rates up to 40 Gb/s are presented for both cross-gain modula
tion (XGM) and cross-phase modulation (XPM) in SOA's demonstrating the
high-speed capability of these techniques.
