Abstract
Recently we presented a novel discretely tunable laser 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 (3 ns) 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 intensity. In was solved by
adding an extra electrode allowing us to control the phase separately. In this paper we
present the new device and study the effect of the control ofthefeedbackphase in order
to improve the performance ofthe original tunable laser concept.
