摘要：

Highly reproducible 1.5μm multielectrode DFB lasers have been fabricated for use as transmitters in frequency shift keying (FSK) transmission systems. These devices were grown using atmospheric pressure metal-organic vapour phase epitaxy and are based on the ridge waveguide structure with a 900μm long cavity. In a 2.4Gbit/s FSK system, sensitivities of- 27dBm were obtained for devices from different wafers under identical biasing conditions. This is the first time that multielectrode DFB lasers have demonstrated the degree of reproducibility required for practical systems. © 1990, The Institution of Electrical Engineers.
