Abstract

Extremely broadband emission is obtained from semiconductor optical amplifiers–superluminescent diodes with nonidentical quantum wells made of InGaAsP/InP materials. The well sequence is experimentally shown to have a significant influence on the emission spectra. With the three In<sub>0.67</sub> Ga<sub>0.33</sub> As<sub>0.72</sub> P<sub>0.28</sub> quantum wells near the n -cladding layer and the two In<sub>0.53</sub> Ga<sub>0.47</sub> As quantum wells near the p -cladding layer, all bounded by In<sub>0.86</sub> Ga<sub>0.14</sub> As<sub>0.3</sub>P<sub>0.7</sub> barriers, the emission spectrum could cover from less than 1.3 to nearly 1.55 µm, and the FWHM could be near 300 nm.
