Modeling of optical wavguides with porous silica claddings and their use in LEAC sensors
MetadataShow full item record
Integrated optical biosensors have many advantages such as low-cost, portability and the ability to detect multiple analytes on a single waveguide. They can be used in many important applications including biosensing applications. Previous research work focused on the issues of design, modeling and measurement of the local evanescent array coupled (LEAC) biosensor. The sensors were made using conventional dielectrics such as SiO2 and SiNx. The large increase in the complexity of the integrated circuits has increased the need for developing low-k dielectrics as new materials to cope with the ...
