摘要：

A spectral linewidth of 170 kHz is achieved at a 1.5-μm wavelength in a 1200-ftm long corrugation-pitch-modulated distributed feedback (DFB) laser having multiple quantum wells (MQW). This is the narrowest linewidth ever reported for InGaAsP DFB lasers. The linewidth-power product is 400 kHz·mW, and the extrapolated residual spectral linewidth is 150 kHz. © 1990 IEEE
