Abstract

This paper describes the performance of a predistorter implementationto a superluminescent diode (SLD) in fiber-optic wireless systems under the optical reflection. SLD intensity noise and 3rd-order intermodulation distortion (IM3) are experimentally compared with those of DFB-and FP-LD. It is observed that the IM3 of SLD has ideal 3rd characteristics and output noise remains unchanged against the number of optical connectors. It is also found that the predistorter reduces IM3 by 8 dB. Receiver sensitivity of the system is discussed From the view point of overall design. The BER performance of an SLD with predistorter using a pi/4-QPSK signal as a subcarrier is also described theoretically and experimentally.
