We present an analytical expression for the 2nd order harmonic distortion caused by spatial hole burning in CATV link DFB lasers. The formula, which readily shows the influence of material and structural parameters, is then used to optimise the device structure for minimum harmonic distortion. A rather unexpected influence of the /spl alpha/-factor is also reported.
