Abstract
We demonstrate wideband reduction of excess intensity noise in an incoherent light source by an optoelectronic feed forward technique. The technique allows significantly narrower optical bandwidths to be used in high-bit rate spectrum-sliced communication systems. We use this technique to successfully transmit data at 2.5 Gb/s over 40 km of standard fiber using a 0.23-nm bandwidth slice of incoherent light. The scheme requires the addition of only a few components to the transmitting node and uses a single optical modulator for data modulation and feedforward noise reduction.
