The characteristics of spontaneous emission  amplified spontaneous emission and modal gain of the MQW is investigated by using single-pass multi-section technique. The amplified spontaneous emission is around a wavelength of 1500nm  dependent on the temperature and the current density. The modal gain spectra show a red shift with increasing temperature. The peak modal gain exhibits a decrease with increasing temperature from 140K to 300K. The loss measurements shows that the main loss mechanism in the structure might be the free carrier absorption in the doped cladding layers and a internal modal loss of about 10cm-1.
