Molecules assembly towards fiber optic nanosensors development

Different optical fiber sensor configurations based on a LBL nano-technique will be presented. With this technique it is possible to fabricate different structures such as nano Fabry Perot interferometers, optical fiber gratings and any other one dimensional photonic bandgap structures that may be used either for sensing applications or for the implementation of other fiber optic devices. Some of the proposed fiber optic sensors have been fabricated and their main characteristics are their negligible temperature dependence, their fast response, the possibility of using low cost LEDs instead of lasers or even the possibility of operating at different wavelengths.
