Dissipation loss of mid-infrared radiation in a dielectric waveguide
- Russian Academy of Sciences, Ioffe Physico-Technical Institute (Russian Federation)
Dissipation loss of electromagnetic radiation with wavelengths of 20-55 {mu}m was theoretically studied in a three-layer planar dielectric insulating waveguide combined with a heterolaser. It was shown that the dependence of the loss on the waveguide layer thickness behaves differently for different wavelengths in the range of 20-55 {mu}m. The lowest loss (several inverse centimeters) is characteristic of radiation with wavelength {lambda} = 20 {mu}m. The losses increase with the wavelength and reach a value of 150 cm{sup -1} at {lambda} = 40 {mu}m, which is almost independent of the waveguide layer thickness. For electromagnetic radiation with {lambda} = 50 and 55 {mu}m, a sharp (hundreds of times) decrease in the loss with an increase in the waveguide layer thickness is observed.
