我们在5 K温度下用波导传输光谱法测量了嵌入光波导中的单个T形1436 nm横向尺寸量子线的吸收光谱。尽管它的体积小，一维激子基态表现出80 cm-1的大吸收系数，或98%的吸收概率为500 m m长的波导单程。(c)2005年美国物理学会。
We measured the absorption spectrum of a single T-shaped 1436 nm lateral-sized quantum wire embedded in an optical waveguide using waveguide-transmission spectroscopy at 5 K. In spite of its small volume, the one-dimensional-exciton ground state shows a large absorption coefficient of 80 cm-1, or a 98% absorption probability for a single pass of the 500 m m long waveguide.
