通过total internal reflection的室温等离子体激元laser

Room temperature plasmon laser by total internal reflection

Ren-Min Ma, Rupert F Oulton, Volker J Sorger, Xiang Zhang

摘要:

等离子体激元激光器在光的衍射极限以下产生并维持强烈的相干光场,具有显著增强光-物质相互作用的独特能力,为生物传感、数据存储、光刻和光通信带来了全新的能力。然而,这些重要的应用需要室温操作,这仍然是一个主要的障碍。本文报道了一种室温半导体等离子体激元激光器,它既具有强腔反馈又具有1/20波长的光限制。强反馈来自于表面等离子体的全内反射,而约束使自发发射率提高了20倍。

英文摘要:

Plasmon lasers create and sustain intense and coherent optical fields below light's diffraction limit with the unique ability to drastically enhance light-matter interactions bringing fundamentally new capabilities to bio-sensing, data storage, photolithography and optical communications. However, these important applications require room temperature operation, which remains a major hurdle. Here, we report a room temperature semiconductor plasmon laser with both strong cavity feedback and optical confinement to 1/20th of the wavelength. The strong feedback arises from total internal reflection of surface plasmons, while the confinement enhances the spontaneous emission rate by up to 20 times.
