Absorption Coefficient of InGaAs V-shaped Quantum Wires Integrated in Optical Waveguides by MBE Growth
Abstract
Optical waveguides with InGaAs quantum wells grown by MBE integrated in the middle of their core are investigated. Photocurrents induced by guided TE and TM modes propagating parallel or perpendicular to the quantum wells have been measured and reflect the anisotropy of the optical matrix element. Spectra of the transmitted intensity of these guided modes have been measured, and the attenuation coefficient of the guided modes due to band edge optical absorption in the quantum wire is established. The attenuation coefficient and the evaluation of the overlap integral beflveen the active nmtenal and the optical inten5ity pen%its to evaluate, for the first time, the absorption coefficient of these quantum wires.
