Kawata's research group Osaka University, looks at various enhanced nonlinear spectroscopic techniques using a metallized tip to enhance the signal of the same, and to minimize the volume of the sample that is probed. The group has developed techniques for tip-enhanced Raman spectroscopy and tip-enhanced coherent Raman spectroscopy, a nonlinear Raman scattering technique that utilizes two lasers to overpopulate the excited state of the system.

and leakage-radiation microscopy to study the propagation of surface plasmons in metallic strip and particle array waveguides, and has applied passive devices such as Bragg reflectors, beam splitters, and plasmon corrals. In addition, this group has applied other techniques such as surface-enhanced Raman scattering to image the fields around plasmonic devices and dark-field microspectroscopy to study the resonant modes of nanowire waveguides.

Watson Laboratory of Applied Physics, California Institute of Tech nology, Pasadena -- This group has explored using nanoparticle chains as plasmonic waveguides. Nanoparticles' plasmon resonances couple to each other via the optical near field, allowing highly localized waveguides that can support sharp bends quite well.

and Scuola Normale Superiore, Pisa, Italy -- This group is focused on the development of novel quantum cascade lasers using intersubband transitions in semiconductor superlattices to generate light in the terahertz spectral region. Toward this end, the group has employed surface plasmons to enhance the overall performance of QCLs and to control the mode structure to produce vertical-emitting single-mode lasers (Tredicucci et al., 2000)
