N. Kobayashi et al., 2,5-Gb/s-1200-km transmission of electroabsorption modulator-integrated DFB laser with quarter-wavelength-shifted corrugation, IEEE PHOTON, 11(8), 1999, pp. 1039-1041
We achieved 2.5-Gb/s-1200-km transmission in standard optical fiber using a
n electorabsorption modulator integrated with a distributed feedback laser
diode having quarter-wavelength shifted corrugation and optimized coupling
in the laser section. several devices from one wafer shelved high optical o
utput power and stable single mode operation. These results showed that our
electroabsorption-modulator-integrated distributed-feedback laser diodes w
ith quarter-wavelength-shifted corrugation are cost effective and have very
long-haul transmission capability.
