从理论上提出了金属约束的微盘激光器的面内多导辐射，可用于同时驱动紧凑型光子集成中的多个元件。基于时域有限差分法和Padé近似，研究了具有横向磁极化和横向电极化的二端口到四端口微盘。通过计算耦合端口与相应模式能量密度分布的匹配决定的模式品质因子（Q），验证了耦合端口的模式过滤作用。半导体微盘的单模激光工作可以通过选择性泵浦来实现。
We theoretically present in-plane multiple guided emissions of metallically confined microdisk lasers which can be applied to drive multiple elements in compact photonic integration at the same time. Two to four-port microdisks with transverse magnetic and electric polarizations are investigated based on finite difference time domain simulation and padé approximation. Modes filtering of coupling ports are verified by the calculated mode quality factors (Q) which are decided by the matching of coupling ports with the energy density distribution of corresponding modes. Single mode lasing operation of semiconductor microdisk with guided emissions is possibly realized by selectively pumping.
