Optical properties of ErFOD-doped polymers and fabrication of channel waveguides

ErFOD-doped P(MMA-co-GMA) (poly-methyl-methacrylate-co-glycidyl-methacrylate) polymer film was synthesized. The NIR photoluminescence (PL) spectrum of the material showed strong characteristic emission of Er3+ ions with broad full width at half-maximum (FWHM) of 55 nm. The rib channel waveguide using ErFOD-doped P(MMA-co-GMA) was designed and fabricated. The loss and gain measurements of the waveguides were also characterized. Further theoretical analysis on Er3+ ions in P(MMA-co-GMA) was performed using Judd-Ofelt theory. The results showed that it is a promising material for the elaboration of laser or optical amplifier.
