摘要：

Linewidths as low as 0.08 nm (-20dB) have been achieved for a three-contact multi-quantum-well (MQW) distributed-feedback (DFB) laser subject to NRZ pseudorandom modulation at 2Gbit/s. These linewidths are substantially narrower than those observed using equivalent single-contact devices, the improved spectral performance being achieved by using the central device region to control the wavelength of the light generated.
