摘要：

Injection-recombination shot noise in the tuning region is identified as significant linewidth broadening mechanism in wavelength-tunable laser diodes. Depending on the tuning efficiency this power independent linewidth broadening is typically around 4-20 MHz. Useful formulas for the evaluation of this broadening and design rules for an improvement of the devices are given. © 1990, The Institution of Electrical Engineers. All rights reserved.
