摘要：

It is shown theoretically and experimentally that optical feedback from the transmission fiber enhances considerably intermodulation and harmonic distortions of laser diodes. Third-order intermodulation distortions up to -15 dBc must be expected for two-tone modulation and low intensity modulation indexes m almost-equal-to 7% per carrier, which would affect the performance of subcarrier multiplexed (SCM) communication systems. To avoid additional distortions the external feedback level must be two orders of magnitudes lower than the critical external feedback level of the laser diode.
