This proposal is related to the demonstration of nanolasers using the property of plasmonic nanostructures developed in our laboratory. We have designed a new structure consisting of a subwavelength structure made of the active material which is embedded between plasmonic nanostructures. Due to the efficient light confinement provided by the sub-wavelength plasmonic plasmonic structure, a low lasing threshold should be obtained and a nanosize light source should be achieved.The last six months of the postdoctoral scholarship were used to characterize the emission of the fabricated nanosize light sources. Optical pumping of the fabricated light sources was used to excite the active material of the plasmonic hybrid structure and the emitted light was recorded with the help of a high resolution spectrometer (~ 1 nm). We observed lasing at room temperature with a full width at half maximum smaller than 1 nm. Also the threshold for lasing was recorded. Unfortunately, the plasmonic mode of the hybrid structure could not yet be confirmed. The project is being pursued and we hope to observe plasmonic modes in the near future.Outstanding Poster Award was attributed to our work at The 8th International Conference on Surface Plasmon Photonics (SPP8), Taipei, Taiwan, May 22-26, 2017.

这个建议是有关的演示纳米激光器使用的等离子体纳米结构在我们的实验室开发的属性。我们设计了一种新的结构，它由嵌入等离子体纳米结构之间的活性材料制成的亚波长结构组成。由于亚波长等离子体激元结构提供了有效的光限制，应获得低的激光阈值，并应实现纳米尺寸的光源。所制造的光源的光泵浦用于激发等离子体激元混合结构的活性材料，并且借助于高分辨率光谱仪（~ lnm）记录所发射的光。我们在室温下观察到激光的半峰全宽小于1 nm。还记录了激光发射的阈值。不幸的是，混合结构的等离子体模式尚未得到证实。该项目正在进行中，我们希望在不久的将来观察到等离子体模式。我们在2017年5月22日至26日在台湾台北举行的第八届表面等离子体光子学国际会议（SPP 8）上的工作荣获杰出海报奖。
