The existence of optical amplification at 1.55 micrometers wavelength in channel waveguides using Erbium dopent and 980 nm laser pump involves an OH and CH3 groups quantity as low as possible. Moreover, a high refractive index variation between the guide and the cladding is necessary to induce a maximum confinement and then increase the dopent efficiency. In this way, we propose a study of different routes we explored to reach this goal: use of F catalysis (to enhance condensation), hybrophobic precursors to reduce the OH quantity, and a diacrylate monomer whose reactivity allows a high refractive index change under UV light exposure.
