Abstract

Pulses from a wavelength-tunable, mode-locked laser diode were measured after 21 km of single-mode fiber propagation by optical sampling with another mode-locked laser diode; a resolution of 0.1 psec/(nm km) is achieved in this chromatic dispersion measurement. In another related experiment, 78-psec-duration pulses from an ordinary, multilongitudinal-mode laser diode are clearly displayed by optical sampling after 36 km of fiber propagation. System bandwidth increases to approximately 500 GHz km as the laser-diode wavelength is temperature tuned through the zero-dispersion region.

Experimental setup; lasers A and B are driven by sine wave plus dc bias, and laser C is driven by comb generator plus dc bias. Both oscillators are synthesizers with frequency offset Δf; a stable, high-level trigger signal is provided by the mixer.

Pulse waveforms after (a) a 2-m-long fiber, no averaging; (b) a 1.8 km-long dispersion-shifted fiber with averaging; and (c) a 21-km-long dispersion unshifted fiber with averaging.

Averaged pulse waveforms from laser B oscillating in multimode (120 psec/division) (a) before and (b)–(e) after 36-km transmission. The center wavelength of the optical source is (a) and (b) 1304 nm, (c) 1307 nm, (d) 1310 nm, and (e) 1315 nm. At 1304 nm the laser-diode spectrum approximately straddles the zero-dispersion wavelength.
