Optical loss and gain

WebThis is due to the comparatively large complex dielectric constant exhibited by metals at optical frequencies. For a wavelength λ = 1μ and a radius a = 0.25 mm, the attenuation for the minimum loss TE 01 mode in an aluminum waveguide is only 1.8 db/km. This loss is doubled for a radius of curvature as short as R ≈ 48 meters.
