Several methods exist to determine the eigenmodes of dielectric waveguides. Semi-analytical methods lead to quick and intuitive results for simple structures. For more complicated waveguide...
Absorption and scattering in low-loss polymer optical waveguides (2007)
Claire Pitois, Anders Hult, Dorothea Wiesmann
The absolute absorption spectra of low-loss optical waveguides, together with their intrinsic and extrinsic scatterings, were measured in the near infrared. Photothermal deflection spectroscopy was...
