We have clarified a mechanism for the degradation of linearity at high temperature, and successfully realized low-distortion 1.3 /spl mu/m DFB lasers operating over a wide-temperature-range. Those lasers can be applied to bi-directional CATV distribution systems without any coolers. A carrier overflow is found to be a dominant factor determining the distortion at high temperatures. Devices with low leakage current have realized low distortion less than -50 dBc at 65/spl deg/C in 78-channel CSO measurements.
