Electroluminescence Spectra of the Near-Infrared InP-Based QuantumWire Lasers
-
Abstract
A near.infrared quantum.wire laser on InP(001)is fabricated.The electroluminescence(EL)spectra under vari· otis currents are measured，which are different from that induced by the filling effect of the energy band.Under relative low current，the EL peak is positioned at a higher energy.Then as the injection current is increased,the high energy peak gradually becomes weak and finally disappears. At the same time，a low energy peak presents，its intensity increases, and it lases up to the threshold current.We deduce that the unique EL spectra with different currents is probably caused by the inhomoge- neous distribution of self-assembled quantum nanostructure size.-
