Abstract :
A novel dynamic light-output versus current (L-I) characteristics measurement is proposed for analyzing intermodulation distortion in CATV link laser diodes (LDs). A good correlation is found between the dynamic L-I characteristics and the intermodulation distortion characteristics in LDs, enabling us to analyze the distortion mechanism in the LDs.
