✦ Synopsis

Abstract

The fabrication and characterization process of BenzoCyclobutene (BCB 4024–40) polymer waveguides are described. The polymer film thickness for various coating speed and refractive index are measured by the method of prism coupling. A cost effective chemical etching technique is used in the waveguide fabrication process to take advantage of the photosensitive nature of the polymer. The waveguide loss is measured using the conventional cut back method which results on an average loss of 3.5 dB/cm. © 2006 Wiley Periodicals, Inc.
