Abstract :
The dynamic spectral width of a CW GaInAsP/InP buried-heterostructure distributed-Bragg-reflector integrated-twin-guide (BH-DBR-ITG) laser operating at a wavelength of 1.58 ¿m was measured under direct modulation up to 3 GHz. The maximum dynamic spectral width at a modulation depth of 100% was measured to be 0.27 nm at the resonance-like frequency of 1.8 GHz. A possibility of wideband transmission of 1.55 ¿m conventional single-mode fibre at 185 Gbit km is suggested.
