From: Maximizing energy coupling to complex plasmonic devices by injecting light into eigenchannels
Phase profiles of the input eigenchannels based on slit separation. (a) and (b) the first eigenchannels for R1 = 550 nm and R2 = 850 nm, respectively. (c and d) the same as (a) and (b), respectively, but for the second eigenchannels. The red dots show the phase of the input eigenchannels obtained from the experiment and the blue curves show the phase of the input eigenchannels calculated using the FDTD method. The positions of the slits are indicated as gray columns. L and R stand for the left- and right-hand slits, respectively.
