Author(s): Goutam Rana, Prathmesh Deshmukh, Shalom Palkhivala, Abhishek Gupta, S. P. Duttagupta, S. S. Prabhu, VenuGopal Achanta, and G. S. Agarwal From quantum optics, we are familiar with electromagnetically induced transparency (EIT), particularly in association with “slow light”. The plasmonic analogue, PIT, now also receives attention due to its potential applications in sensing, communication, and more. However, the conventional dipole-quadrupole coupling yields only a modest quality factor Q 〈 100 . Here controlling the Q factor of the Fano lineshape is not trivial. The authors demonstrate quadrupole-quadrupole interaction in engineered meta-atoms to control Q and attain Q 〉 100 , with the potential to reach 1000, bringing high- Q applications based on PIT one step closer.
