Scheme 1. Probe Location (A, below, or B, above, the Ag Film)-Dependent Coupling Modes from the Tamm Structure.

As shown schematically, TSCE with 637 nm emission maximum is expected to couple to surface to normal from this structure, whereas the surface plasmon-coupled emission (SPCE) shows typical circular cone emission at about 48° off-axis from surface normal. Free space emission is isotropic above the surface. Also shown in the figure are Tamm (blue line) and SPR (red line) field locations in the structure.
