Abstract
Planar wave guide 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 degree(s)C. Insertion loss and polarization-dependent loss showed no increase at temperatures up to 257 degree(s)C. The reflected spectrum of a Bragg grating showed no monotonic change in (lambda) B, width, or strength in 105 days at 125 degree(s)C. Humidity changes from 0 to 90%RH caused a reversible blue shift in (lambda) B of only 0.00004. Light flux of 130mW exhibited no impact on n, (delta) n, or IL. Heaters showed no degradation at 85 degree(s)C/85%RH. Bonding to substrate, heaters, and pigtails remained intact throughout the testing.
