Abstract

A polymer-based, optical waveguide with an integrated coupling prism and microlenses was designed and fabricated to improve overall optical performances. The use of flycutting allowed accurate control of the polymer waveguide thickness. A large prism facilitated better coupling of the light to the waveguide. The highest intensity evanescent excitation of the waveguide was obtained at the critical angle of the waveguide. Fluorescent radiation was highly focused by the array of microlenses. The microfabricated waveguide will allow the rapid, low-cost detection of the fluorescent samples in biomedical applications.
