Abstract

Summary form only given. The aim of the paper is to show the impact of the modal gain saturation on the tuning-range as well as the tuning rate of three-contact DFB lasers (and filters) at single current modulation. Taking into account the modal gain saturation due to gain-curve-shift, we have demonstrated theoretically and experimentally the feasibility of a wide wavelength tuning (2.5 nm) and a high tuning rate with a small power change by single (lateral) current tuning in the case of three-contact DFB lasers and filters
