A laser, including a grating structure consisting of two or more gratings generating a plurality of different wavelength peaks for reflection of optical radiation therefrom. The laser also includes a semiconductor device having a gain region which is operative to amplify the optical radiation, and a wavelength tunable filter (WTF) region which is adapted to filter the optical radiation. The device is optically coupled to the grating structure so as to define a laser cavity having a plurality of cavity modes. The cavity modes are selected by tuning a wavelength pass-band of the WTF region to overlap with one of the wavelength peaks of the grating structure.
