Nonlinear Electromagnetics in Negative Index Metamaterials
The paper reviews several schemes of nonlinear-optical coupling between the ordinary and backward electromagnetic waves in negative-index metamaterials,which meet the requirements of phase matching.They are aimed at applications to compensating strong losses inherent to plasmonic metamaterials and to design of novel photonic devices for optical sensing and data processing.The outlined possibilities of implementation of originally strongly absorbing microscopic samples of plasmonic metal-dielectric composites for the remote all-optically tailoring of their transparency and reflectivity as well as the options for creating of unique ultracompact photonic sensing devices are demonstrated through numerical simulations.Different schemes of coherent energy transfer from strong control field to the negative-index signals described here present the approach to compensating losses in the plasmonic metamaterials alternative to that based on the population inversion.It turned out that similar extraordinary distributed-feedback nonlinear-optical propagation processes are possible through Raman scattering on optical phonons having negative dispersion and negative group velocity.
