ABSTRACT:
The modulation bandwidth of a long-cavity semiconductor laser and a multi-frequency long-cavity semiconductor laser is increased by electronic precompensation of the modulation input. The modulation bandwidth may be further increased by having the modulated amplifier and the desired output as far apart as possible.
