Strained‐layer multiquantum‐well distributed‐feedback (SL‐MQW‐DFB) lasers at a wavelength of 1.55 μm operating from −40°C to 85°C without any coolers are demonstrated. The average value of IMD3 at 1.8 GHz and 5 mW operating conditions was −71 dBc, and the RIN at 2 mW was measured as 151 dB/Hz. The uncooled DFB lasers we have developed are very useful for mobile applications. © 2005 Wiley Periodicals, Inc.
