Accelerated Aging of Tunable Thermo-optic Polymer Planar Waveguide Devices made of FLuorinated Acrylates

摘要

Planar waveguide device components, made from photocurable fluoroacrylates, demonstrated stability under conditions that exceed those needed to operate planar polymer thermo-optic switches. Fluoroacrylate polymers exhibited negligible decomposition at 200 deg C. Insertion loss and polarization-dependent loss showed no increase at temperatures up to 257 deg C. The reflected spectrum of a Bragg grating showed no monotonic change in lambda_B, width, or strenght in 105 days at 125 deg C. Humidity changes from 0 to 90
