| Abstract: | In this paper, the compression experiments of picosecond optical pulses from a gain-switched InGaAsP distributed feedback (DFB) laser at a 1.5 μm wavelength range using a Gires-Tournois (G-T) interferometer are reported. Ultrashort optical pulses with a pulsewidth of 6.6 ps, repetition rate of 2.4 GHz, and peak power in excess of 200 mW are obtained. The compression ratio is close to 5. The explanation for the experimental results is given, and the pulse's compression characteristics of a G-T inteferometer are discussed by a computer simulation analysis. |
