Abstract

Recently we presented a novel discretely tunable that consists of a Fabry-Perot laser which was forced to operate in single-mode condition by applying on-chip filtered feedback. The laser switches extremely fast and requires simple on/off control currents to switch the wavelength. In these first devices it was not possible to control the phase of the feedback light independently from the feedback intesity. In was solved by adding an extra electrode allowing us to control the phrase seperatly. In this paper we present the new device and study the effect of the control of the feedback phase in order to improve the performance of the original tunable laser concept.
