摘要：

The spectral linewidth of MQW λ/4-shifted DFB lasers has been reduced by increasing KL up to 3-4 without degradation of side-mode suppression by the spatial hole burning effect. A narrow sub-MHz (0.79 MHz) spectral linewidth is achieved for the first time in conventional 300-400μm long cavity DFB lasers. © 1990, The Institution of Electrical Engineers. All rights reserved.
