100 GHz optical pulse generation using Fabry-Perotlaser under continuous wave operation

Optical pulse generation at 100 GHz using a 1.5 µm Fabry-Perot laser is experimentally demonstrated under continuous wave operation. Although the output from the laser is almost constant, sub-picosecond short pulses at 100 GHz are obtained after propagation through a singlemode fibre. The measured radio frequency spectrum confirms that the Fabry-Perot laser is passively modelocked.
