We have experimentally studied the non-resonant enhancement of spontaneous emission of HITC laser dye in metal-insulator-metal (MIM) waveguides (also referred to as Fabry–Perot cavities). We have found that in the cavities, whose size was too small to support a fundamental or any higher order resonance, the emission decay rate increased, by nearly an order of magnitude, with reduction of the cavity size. At the same time, the emission intensity increased when the cavity size was reduced from ∼200 to ∼30 nm and dropped sharply when the cavity was smaller than ∼30 nm. This emission enhancement, consistent with the perpendicular orientation of the emitting dipole with respect to the mirrors, is in a good agreement with the theoretical predictions known from the literature. |
