| Abstract(in English) | Energy-band structures of compressively-strained GaInAsP/InP quantum-wires fabricated by etching and regrowth method have been calculated using an 8 band k ・ p theory including strain relaxation. The effects of strain-compensating barriers and vertically stacking multiple wire layers on band structures are investigated. Experimentally observed wire-width dependence of the large energy blue-shift in vertically stacked multiple quantum-wire structures is accurately explained using our calculations without any fitting parameter. Polarization dependence of spontaneous emission spectrum of the strained quantum wires are studied theoretically considering the effects of strain and vertically stacking multiple wires. An anomalous dependence of polarization anisotropy on compressive strain in active regions, barrier tensile strain, wire width and the number of vertically stacked layers is explained in terms of band mixing due to strain relaxation. |
