Paper Abstract

We theoretically and experimentally investigate a recently proposed integrated tunable laser which consists of a curved waveguide distributed-feedback (DFB) laser and a passive electroabsorption (EA) modulator-separated by an isolation section. The modulator provides wavelength selectivity in the integrated device. The facet at the laser side is anti- reflection (AR) coated to enhance the light output power, and the EA side facet is high-reflection (HR) coated to increase the coupling between the two sections. We have developed a transfer-matrix model based on the coupled-mode theory which takes into account the curved waveguide and above-threshold spatial hole burning effects. Using this model, we study the wavelength tuning behavior of the integrated device when a voltage bias is applied to the modulator section.
