Abstract

Evidence of tunneling and electronic coupling in a one-dimensional system is reported. This is accomplished by comparing low-temperature photoluminescence and photoluminescence excitation spectra of GaAs double quantum wires of different barrier widths with a full $4 \times 4 k \cdot p$ calculation of coupled interband transitions.
