1.55-mu m DFB lasers over a wide temperature range for analog application

Abstract

Strained-layer multiquantum-well distributed-feedback (SL-MQW-DFB) lasers at a wavelength of 1.55 mu m operating from -40 degrees C to 85 degrees C without any coolers are demonstrated. The average value of IMD3 at 1.8 GH7 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. (C) 2005 Wiley Periodicals, Inc.
