| Abstract: | The intensity fluctuation of a longitudinal mode in a modulated dynamic single-mode laser consisting of a 1.6 ?m GaInAsP/InP buried-heterostructure laser with butt-jointed built-in distributed-Bragg-reflector (BH-BJB-DBR) was suppressed to 30 dB less than that of a conventional laser. The possibility of wideband single-mode-fibre communications in the 1.5?1.6 ?m wavelength region without degradation of the bandwidth caused by mode partition noise is suggested. |
