Abstract :
Superluminescent diodes with broad emission bandwidth characteristics and the mechanism of carrier distribution in the active layer are explored. Using InP substrate with five 6 nm InGaAsP quantum wells and two 15 nm InGaAs quantum wells, we get a very broad emission spectrum. The spectral width is nearly 400 nm, almost covering the range from 1250 nm to 1650 nm.
