Fast wavelength switching based on a Fabry-Perot laser pair using optical injection

Abstract

We propose and experimentally demonstrate a new fast wavelength-selectable laser technique, which is based on Fabry-Perot (FP) lasers with external light wave injection. By using different bias Currents of FP lasers, wavelength tuning can be realized. In the experiment, the tuning of three different wavelengths tuning, the side-mode suppression ratio of >20dB, and the wavelength switching time of <2 ns were attained.
