Abstract :
Experimental studies of subharmonic modulation distortions of semiconductor lasers with optical feedback are described. These distortions were found to exhibit almost resonant frequency characteristics and threshold behaviour against the modulation frequency and its depth, respectively. It was inferred that they would be excited by parametric interactions caused by some laser diode parameter changes due to modulation.
