Abstract
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.
