Comparable optical properties to silica were shown by our 1x32 splitter polymer optical waveguide with dopant-free perfluoropolymer core. Insertion losses and polarization dependent losses at 1.31, 1.55, and even 1.65um were <16.3dB, <0.15dB, respectively.
We fabricated single mode optical waveguides made of perfluoropolymers with extremely low propagation loss at communication wavelengths reaching even 1650 nm, and found they showed high reliability. The used materials are poly(perfluorinated butenyl vinyl ether) and the chemically-related materials. In this paper we report on the perfluoropolymer optical waveguides with dopant-free core, while we...
Polarization independent and low propagation loss of 0.03 dB/cm even at 1650 nm was obtained by the polymer optical waveguide with the dopant-free core made of purely perfluorinated amorphous polymer. High durability to humidity was also shown
A 3dB insertion loss 16 16 channel arrayed-waveguide grating (AWG) multi/demultiplexer has been realized based on low absorption loss (<0.001dB/cm) perfluorinated polymers. A temperature dependence of -0.5pm/C was achieved by a novel superstrate tuning technique.
