Polymeric optical waveguides

The present work describes the characterization of internally developed epoxy ridge optical waveguides which exhibit low propagation loss (0.3 dB/cm at 1.3 μm), high environmental stability (low sensitivity to moisture), have smooth walls (100 nm sidewall roughness), and high temperature stability (275°C). The techniques used to fabricate these waveguides are compatible with the planar processes used in the manufacture of high performance electronic packages. © 1990 SPIE.
