Abstract
By using an external light-injected multiple-quantum-well (MQW) semico nductor optical amplifier (SOA), we have demonstrated a 100-km optical fiber link that transports 77 channels of 63-QAM signals. This is equ ivalent to a system capacity of 2.3 Gb/s, while using a laser bandwidt h of only 550 MHz. Under a requirement of carrier to noise and nonline ar distortion ratio of 30 dB per channel, the 1310-nm gain-peaked SOA input dynamic range was increased from 0 to 9 dB due to an injected li ght with 8.8 dBm and a wavelength of 1283 nm.
