Multi-gigabit short pulse generation from integrated DBR laser/modulators

The generation of short optical pulses at 1.5 /spl mu/m is a key issue in future communications systems. Recently, a new approach to pulse generation has been reported in which the output ofa CW laser is converted to nearly transform limited pulses by a sinusoidally driven electro-absorption modulator. This simple technique is readily integrated and provides flexibility in both operating frequency and wavelength, an important asset for soliton and optical time division multiplexing (OTDM) applications.
