Abstract

A new fast tunable laser technique, which is based on a Fabry-Pe´rot (FP) laser pair with optical interinjection, has been proposed and experimentally demonstrated. By adjusting different bias currents of FP lasers, the wavelength tuning can be realized. In the experimental demonstration, a 2.3-nm tuning range with three different wavelengths, the sidemode suppression ratio (SMSR) of >20 dB, and the wavelength switching time of <6.8 ns have been reached. In addition, the SMSR performance versus injection power level has also been investigated. This tunable laser has the advantage of simple architecture, data direct modulation, and fast wavelength tuning.
