Abstract
Cleaved-edge overgrown semiconductor quantum wires containing a one-dimensional electron gas with few occupied subbands are probed by optical experiments. Inter-sub-band excitation modes are observed by resonant inelastic light scattering at energies that agree well with theoretical estimates obtained within the Fermi-liquid model. Narrow spectral line-shapes indicate high uniformity and long electron scattering lengths that are consistent with recent transport measurements.
