用optical fiber锥形波导测量含量子点半导体微盘谐振器的光致发光

Photoluminescence measurements of quantum-dot-containing semiconductor microdisk resonators using optical fiber taper waveguides

Kartik Srinivasan, Andreas Stintz, Sanjay Krishna, Oskar Painter

摘要:

采用光纤锥形波导提高了嵌入自组装InAs量子点的AlGaAs微盘谐振腔的室温光致发光测量效率。作为一种近场收集光学器件,与传统的垂直入射自由空间收集技术相比,光纤锥形将微盘激光器的收集效率提高了约15-100倍。此外,光纤锥形可以作为一种有效的手段,用于泵浦这些设备,并采用光纤泵浦和收集的初步测量。这项工作对基于芯片的腔量子电动力学实验的影响进行了讨论。

英文摘要:

Fiber taper waveguides are used to improve the efficiency of room temperature photoluminescence measurements of AlGaAs microdisk resonant cavities with embedded self-assembled InAs quantum dots. As a near-field collection optic, the fiber taper improves the collection efficiency from microdisk lasers by a factor of ~ 15-100 times in comparison to conventional normal incidence free-space collection techniques. In addition, the fiber taper can serve as a efficient means for pumping these devices, and initial measurements employing fiber pumping and collection are presented. Implications of this work towards chip-based cavity quantum electrodynamics experiments are discussed.
