Abstract

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 wax -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.
