Experimental results exhibit superior device characteristics with low threshold of 19 mA  output light power of 4.5 mW  and over 20 dB extinction ratio when coupled to a single mode fibre. Moreover  over 10 GHz modulation bandwidth is developed with a driving voltage of 2 V. Using this sinusoidal voltage driven integrated device  10 GHz repetition rate pulse with an actual width of 13.7 ps without any compression elements is obtained.
