    Abstract

    A monolithic integration of ten distributed feedback lasers with a 10×1 multimode-interference optical combiner using the selective area growth technology is proposed and demonstrated. In the device, Titanium film thermal resistance for wavelength tuning are integrated with a novel procedure. The device is mounted on heat sink and tested at 20 ℃. The average channel spacing of the device is 1.29 nm. The average output power of lasers is 0.5 mW with a current of 200 mA and threshold currents of 25~30 mA. The tuning efficiency of integrated thermal resistance is about 5 nm/W. The integrated device can cover 34 channels on the 50 GHz ITU (international telecommunication union) grid with a suitable heating power, which can operate separately or simultaneously.
