High-Q and low-Q modes in a single rectangular nanowire (NW) with TE polarization.

Caption

High-Q and low-Q modes in a single rectangular nanowire (NW) with TE polarization: (a) Eigenfrequencies for modes TE(3,5) and TE(5,3) as a function of size ratio of NW. (c) Q-factors of modes TE(3,5) and TE(5,3) as a function of size ratio. (c) Multipole analysis on eigenfields of modes TE(3,5) and TE(5,3). (d) The top panel is a decomposition of TE(3,5) for the rectangular NW into eigenmodes for the circular NW, and the bottom pane is decomposition of TE(5,3) for the rectangular NW into eigenmodes for the circular nanowire.
