Paper Abstract
We studied both experimentally and numerically the spectral behavior of modal birefringence in channel waveguides
inscribed in PMMA by DUV illumination. The measurements of birefringence were carried out using spectral
interference method for different waveguide widths, respectively 2, 3, 4, 5, 6 μm which were inscribed using 3 J/cm2.
We have also modeled the spectral dependence of birefringence related only to waveguide geometry using FEM method.
High discrepancy reaching one order of magnitude was observed between measured and calculated birefringence. This is
related to the fact that numerical analysis accounts only for so called geometrical birefringence induced by the
asymmetry of the waveguide, while in measurements the overall modal birefringence relates to both the geometrical and
the material effect. Our measurement results indicate that the contribution of the material birefringence in the analyzed
waveguides may reach up to 3×10-4 in a short wavelength range.
