Abstract
We measured intermodulation distortion (IMD) generated by the presence of two optical tones separated by up to 1 GHz in a 1.3μm near-travelling-wave optical amplifier. The measured distortion agrees with calculations of third-order nonlinearity caused by carrier-density modulation. The third-order intercept of 5dBm may be more restrictive in closely spaced frequency-multiplexed systems than gain saturation.Keywords
