We present a novel integrated tunable laser based on filtered feedback, which combines a simple tuning method with ns switching speed. Introduction Tunable lasers are widely used in telecommunication networks nowadays because they allow flexible reconfiguration of the network and reduce inventory cost for network operators [1]. Most widely tunable lasers employ two Distributed Bragg Reflector (DBR) tuning sections with a comb-like filter response, where the Vernier effect is used to realize a large tuning range with a relatively small tuning range for each of the filters. In this scheme, two control currents are needed for the two DBR mirrors, a third one for controlling the phase, and also the current through the amplifier section needs to be accurately controlled. A tuning table is needed for finding the proper control currents to hit a specified wavelength. Such lasers are available with high power (> 10 dBm), a wide tuning range (> 40 nm) and tuning speeds in the ms-range [2]. So far, attempts to simplify the control scheme have not yet led to competitive devices. We have invented a novel discrete tuning mechanism based on filtered feedback, which combines simple wavelength control with very high switching speed [3]. The principle of this Integrated Filtered Feedback Tunable Laser (IFF-TL) has first been demonstrated by Matsuo et al [4], where two coupled micro-ring filters were used for controlling the wavelength. It was shown that with this approach the frequency drift can be reduced below 1 GHz. In this paper we present a laser which uses a compact AWG integrated with short SOA gate switches for controlling the wavelength. In an earlier paper [5] we have shown that these short gate switches allow for switching times of a few ns. In this paper we demonstrate that the filtered feedback principle in combination with an AWG and a SOA gate switch array allows for simple and stable tuning. The fast tuning time makes the device suitable for packet switching applications.
