In this paper, a theoretical and experimental study of intermodulation and harmonic distortion in high-speed 1.3 and 1.5 GHz InGaAsP lasers modulated at frequencies up to 8 GHz is presented.Abstract:
A theoretical and experimental study is presented of intermodulation and harmonic distortion in high-speed 1.3 and 1.5 ?m InGaAsP lasers modulated at frequencies up to 8 GHz. It is found that all lasers measured, including Fabry-Perot and distributed feedback lasers, generate approximately the same distortion levels for a given modulation depth and relaxation resonance frequency. There are minor differences between lasers, which result from differences in the damping of the small-signal resonance peak.read more

TL;DR: In this article, the third order intermodulation distortion product in the modulation response of high speed semiconductor lasers was investigated and it was shown that at low frequencies, an increase at a rate of 40 dB/dec as the modulation frequency is increased, and a leveling off at one half of the relaxation oscillation resonance frequency.

TL;DR: In this paper, the harmonic distortion caused by laser diodes is analyzed analytically and it is shown that the spontaneous-emission factor, the diffusion factor, and the photon lifetime in the cavity play central roles for the evaluation of distortion.
