Backward electromagnetic waves are extraordinary waves with contra-directed phase velocity and energy flux. Unusual properties of the coherent nonlinear optical coupling of the ph Efficient second harmonic generation from mid-infrared to second harmonic generation (SHG) processes in LiNbO3 and AlGaAs-based HPW, respectively. However, the non-linear HPW they proposed are not compatible with sili-con photonics. In this Letter, we propose a silicon-organic hybrid plasmonic waveguide (SOHPW) easily amenable to fabrication with a nonlinear polymer (NP) in the slot, as shown in Fig. 1.
