Integrated Nanocavity Plasmon Light Sources for On-Chip
Next generation on-chip light sources require high modulation bandwidth compact footprint and efficient power consumption. Plasmon-based sources are able to address the footprint challenge set by both the diffraction limited of light and internal laser physics such as plasmon utilization. However the high losses large plasmonic-momentum of these sources hinder efficient light coupling to

Near-field digital holography a tool for plasmon phase
In this work we propose a novel method for the measurement of the phase distribution of the near electric field based on the principles of phase-shifting digital holography. In contrast to previous methods the holographic interference occurs already in the near field and the phase distribution can be determined purely from the scanning near

At low frequency an SPP approaches a Sommerfeld-Zenneck wave where the dispersion relation (relation between frequency and wavevector) is the same as in free space.At a higher frequency the dispersion relation bends over and reaches an asymptotic limit called the "plasma frequency" (see figure at right). For more details see surface plasmon polariton.
