Abstract :
We present a pre-distorter model derived from a modified semiconductor user model that reduces the nonlinear distortion in directly modulated semiconductor lasers. Simulation results showing improvements greater than 40dB for the second harmonic and the second and third order intermodulation distortion components over a wide frequency range are given. Performance and capability of the pre-distorter are examined for two different lasers (Ortel 1510B and Fujitsu FLD3F7CZ) under different operating conditions
