Waveguide Characterization and Biosensor Modeling: Introduction to biosensors and Optical Waveguide Characterization.

'Waveguide Characterization and Biosensor Modeling' covers diverse topics including wave optics, lithography techniques and optical waveguide characterization. The book begins with an introduction to biosensors development and description of SPARROW biosensor. Wave optics and interaction of light at the boundaries are discussed to help understand light propagation in waveguides. Chapter 2 discusses the theoretical background of symmetrical and symmetrical waveguides along with a brief introduction to topics like coupled mode theory and frustrated total internal reflection. Prominent loss mechanisms in the waveguides have been discussed including absorption, scattering and radiation losses. Evanescent wave and the importance of penetration depth for the operation of SPARROW biosensor have been explained in detail. Modal analysis required for modeling the biosensor has been studied in detail. Waveguide loss calculation using image processing techniques has also been discussed. PDMS mold preparation and bonding to alumina surface is discussed. This should be a interesting book to all students and would give exposure to current techniques.
