Paper Abstract

This paper describes a 1.3-micrometers edge-emitting LED (light-emitting diode) with multiple quantum well structure. We introduce quantum well structure to the emission region in order to improve the thermal stability of the optical output power. The least temperature dependence and the highest optical output power are obtained at ten quantum wells. In the range from -30 degree(s)C to 85 degree(s)C, the temperature coefficient of the optical output power and the peak wavelength are - 0.87%/ degree(s)C, 0.52 nm/ degree(s)C, respectively. The LED yields a coupled power of 20 (mu) W into a single-mode fiber at a driving current of 100 mA and 25 degree(s)C.
