We report a method for direct generation of voltage programmable, arbitrarily shaped laser pulses of subpicosecond duration and roughly 100 fs resolution. A waveguide intensity modulator was fabricated and incorporated into a fiber-grating pulse compressor to shape temporally the chirped pulse before compression. Optical pulses with sin(x)/x and square envelopes are synthesized to demonstrate the technique.

shadows and interference. Occasionally, software parameters such as handoff thresholds and cell-power budgets are also adjusted. While hardware parameters are easily set during network installation, they are hard to change afterward. As a result, the optimization with respect to hardware parameters occurs during network planning and deployment, and it is only repeated in areas where performance problems or infrastructure upgrades are required. Since it is performed as a singular event, the optimization process is
