We report measurements of hot-carrier photoluminescence from GaAs V-groove quantum wires. CW spectra reveal distinct one-dimensional subbands: at low excitation density recombination from laterally confined nv=1 states is dominant, which shows that c

Trapping into the active region is one of the most important design considerations in quantum well lasers. This process becomes crucial for the operation of quantum wire devices since the very small active volume demands strong coupling to the extern

Epitaxial growth on nonplanar substrates is an attractive method for producing high quality quantum wire structures for applications in low-threshold lasers. However, a crucial factor in this application is the transfer of carriers between extended (

Raman spectroscopy has been used to measure phonons in GaAs v-groove quantum wire structures containing (001) and (111) GaAs/AlAs superlattice barrier regions. Resonance enhancement permits the identification of modes in different regions of the stru

We have determined the main parameters of the quasi-one-dimensional excitons confined in GaAs V-shaped quantum wires, namely exciton Bohr radius and binding energy, by two-photon absorption and magnetoluminescence experiments. The experimental result

We have investigated the optical properties of excitons in GaAs quantum wires grown on nonplanar patterned substrates (V-shaped quantum wires) by photoluminescence and magnetophotoluminescence. The experimentally observed transitions are in agreement

We have measured hot carrier relaxation in GaAs V-groove quantum wires using time-resolved photoluminescence. Relaxation between confined one-dimensional subbands is clearly observed on the time scale of several hundred picoseconds. A simulation of t

Hot carrier dynamics in semiconductor quantum wires is the subject of much current interest, since unique characteristics of inter- and intra-subband carrier-carrier (CC) and carrier-phonon (CP) interactions in quasi-one-dimensional (ID) systems have
