Effect of the Propagation Loss on the Cherenkov SHG in a Channel Waveguide
Based on the coupled mode theory, second harmonic generation (SHG) in the form of Cherenkov radiation from a channel waveguide has been investigated taking the propagation loss into account. The results show that the conversion efficiency has an exponential behaviour and a saturation characteristic, which differ from the linear behaviour in the case of omitting the propagation loss. The results play an important role in the design and fabrication of Cherenkov frequency doubler.
