Abstract

MBE (Molecular Beam Epitaxy) grown p-i-n laser heterostructure, based on InAs/InP Quantum Dashes with quaternary InGaAsP Quantum Well, were investigated through electroluminescence (EL) measurements. Bipolar injection set on just of forward bias,VF, ≅1.3 V, resulting an emission of long wavelength laser light, peaking of 1550 nm. This value was consistent with thermal energy band gap, deduced from current-voltage measurement in space charge limited regime where mobility of injected carriers followed Poole-Frenkel type conduction.

Keywords

EL, quantum dashes, and annihilation.
