Polymer based optical waveguides

Optical waveguides are structures that confine and direct optical signals in a region of higher effective index than its surrounding media. For integrated optics and photonic applications, it is often of importance to prepare waveguides in the form of thin film structures. Polymeric materials are pa...

Polymer based optical waveguides
description Optical waveguides are structures that confine and direct optical signals in a region of higher effective index than its surrounding media. For integrated optics and photonic applications, it is often of importance to prepare waveguides in the form of thin film structures. Polymeric materials are particularly attractive in integrated optics because of their ability to be processed rapidly, cost-effectively, and with high yields. Polymeric materials are allowed to form compact optical circuits by offering large refractive index contrasts. A new polymeric material: CYCLOTENE™ PhotoBCB 4024-40 from DOW® Chemical had been adopted in this study for the development of optical waveguides. The behavior of light propagation and the confinement of light in a polymer based optical waveguide had been investigated. The characteristics of the waveguide had been simulated by finite difference method in MATLAB programming environment to obtain the optimum structure for waveguide fabrication.
