Resonator channel drop filters in a plasmon-polaritons metal

Abstract

Channel drop filters in a plasmon-polaritons metal are studied. It shows that light can be efficiently dropped. Results obtained by the FDTD method are consistent with those from coupled mode theory. It also shows, without considering the loss of the metal, that the quality factor for the channel drop system reaches 4000. The quality factor decreases significantly if we take into account the loss, which also leads to a weak drop efficiency.
