| Abstract(in English) | GaInAsP/InP quantum-wire lasers were fabricated by electron-beam lithography, wet-chemical etching and 2-step organometallic vapor phase epitaxy growth, and compared with quantum-film lasers fabricated on the same wafer. As a result, better lasing properties, such as low threshold current and high defferential quantum efficiency of quantum-wire lasers over quantum-film lasers were obtained at T<200K. An internal quantum efficiency of the quantum-wire lasers was evaluated to be almost 100% up to 200K from the cavity length dependence of differential quantum efficiency. Furthermore, gain spectra of quantum-wire lasers as well as quantum-film lasers were measured. As the result, narrower material gain spectrum of quantum-wire lasers was observed at T=100K. |
