Kk. Chow et C. Shu, Spectrally resolved analysis of fast tuning in single-mode pulses generated from mutually injection-seeded Fabry-Perot laser diodes, IEEE PHOTON, 12(11), 2000, pp. 1444-1446
Electrically wavelength-tunable pulses are generated from two mutually inje
ction-seeded Fabry-Perot laser diodes at 1 GHz. By investigating the spectr
al dynamics, we experimentally show that stable single-mode output can be o
btained after four roundtrip propagation cycles in the external cavity. We
also probe the dynamic change of the spectrum during the switching between
two single-mode wavelengths. It is found that the steady states can be reac
hed after six to seven roundtrip cycles.
