Abstract:Integrated circuit components have nowadays reached dimensions much smaller than the dimensions oftypical micro-optical components. This “size mismatch” is regarded as a practical concern for a variety of integrated optics applications. The application of surface plasmon polaritons (SPPs) generated at metal/dielectric interfaces provides light confinement and control at length scales below 100 nm, herewith overcoming this size mismatch [1], [2]. The SPP can propagate with an effective wavelength much smaller than the free-space wavelength of photons at the same frequency. In contemporary SPP research, plasmons are normally generated by external lasers. In a recent article [2] we have presented an electrical SPP source (shown in Fig. 1), operating at low supply voltage, and manufactured using CMOS backend compatible techniques. When a current is applied to our device, we observe emission at the location of the out-coupling grating array.
