Lasing Action from Destructive Interference of Optical Multipole Resonances |
| 초록 |
I will discuss the formation of the bound state in the continuum (BIC) in two dimensional nanopillar arrays of TiO2 by destructive interference of multipole resonances. Three types of BICs originated from vertical magnetic dipole (MD), vertical electric dipole (ED), and magnetic quadrupole (MQ) are observed experimentally with the supports of Finite Element Method simulations and multi-decomposition analysis. Moreover, by incorporating CdSe/CdxZn1-xS core-shell nanoplatelets as a gain medium into these TiO2 nanostructures, optically pumped lasing at room temperature from MD-BIC and MQ-BIC are demonstrated. This study suggests a novel way to design laser cavities that may find applications in many optoelectronic applications. |
