Abstract

Recent developments in fabrication characterization and understanding of local surface plasmon resonances and surface plasmon waveguides have fuelled the development of a new generation of surface plasmon based biosensors mainly based on local refractive index sensing and surface enhanced Raman scattering 1 2 Although the actual sensor has scaled to the nanoscale the system still requires bulky optical components such as light sources lenses objectives and detectors Integrating sources and/or detectors with the plasmonic sensor can pave the way to smallfootprint photodetectors In this chapter we demonstrate direct electrical detection of surface plasmon resonators and integrated detection and generation of deepsubwavelength guided plasmons in metalinsulatormetal MIM waveguides We will discuss these different devices including optical/electrical characterization the comparison with simulations and their relevance for integrated biosensors
