Abstract

The feasibility for generating bandwidth-limited, single-longitudinal-mode, ultrashort optical pulses has been demonstrated for the first time using a DBR diode laser at 1.3 μm by the method of strong RF modulation superimposed on the DC bias current. The time-bandwidth product of generated picosecond pulses at 400 MHz modulation frequency was measured to be 0.45 for the Lorentzian pulse shape with FWHM of approximately 31.5 ps.
