Guided-wave electron optics for the integration of nanophotonic devices with nanoelectronic devices

Abstract

In this work we present an analysis of the propagation, based on the Dirac equation, of spinor-electron quantum modes, that is, of spinor-electron guided waves in asymmetric 2D and 1D semiconductor nanostructures. Spinor-electron modes are calculated by means of Dirac equation in an asymmetric 2D semiconductor structures, analogous to the wellknown optical modes of the conventional integrated optics; moreover, by means of standard methods well stablished in integrated photonics, such as Marcatili method or Knox-Toulios method, 1D electron waveguides are studied. The study of these nanoelectronic devices based on electron waveguides in semiconductors is directed to understand better the possibilities of linking between nanoelectronic and nanophotonic devices.
