研究目的
To propose a theory for the waveguide design and analysis for plasmonic nanolasers and extend it to plasmonic four-wave mixing (FWM) devices, aiming to address long-standing challenges in plasmonic nanolasers and nonlinear optical devices.
研究成果
The proposed theory for waveguide design and analysis for plasmonic nanolasers, extended to plasmonic FWM devices, leads to the discovery of novel and superior waveguide configurations. These configurations, such as MHD?HA, have the potential to revolutionize plasmonic nanolasers and nonlinear devices by achieving low threshold, electrically pumped nanolasers, or highly efficient, low-driving power DFWM devices.
研究不足
The study assumes the modal loss dominates for plasmonic waveguides and neglects quenching effects initially. It also enforces restrictions for nonlinear devices, such as the dominance of one highly nonlinear dielectric and operation away from the plasma wavelength of the metal.
1：Experimental Design and Method Selection:
The study starts from the fundamental requirements for the waveguide for high-performance nanolasers, focusing on enhanced spontaneous emission and low threshold gain. It explores one-dimensional plasmonic waveguide configurations and extends to 2D structures.
2：Sample Selection and Data Sources:
The study considers five materials for the waveguide configurations: an active medium with gain, metal, low-index and high-index dielectrics, and air.
3：List of Experimental Equipment and Materials:
Materials include silver for metal, erbium-doped silicate glass and organic–inorganic CH3NH3PbI3 perovskite for the active medium, MgF2 for the low-index dielectric, and Si and AlAs for the high-index dielectric.
4：Experimental Procedures and Operational Workflow:
The study systematically explores all possible configurations of plasmonic waveguides with up to five layers, optimizing their performance as nanolasers at two operating wavelengths: 1550 nm and 790 nm.
5：Data Analysis Methods:
The performance of each configuration is evaluated based on the Purcell factor, effective area, threshold gain, and gain confinement factor.
