Molecularly self-assembled optical fiber sensors

Different optical fiber sensors based on the electrostatic self-assembly (ESA) method will be presented. With this technique it is possible to fabricate different structures such as nano Fabry Perot interferometers and optical gratings that may be used either for sensing applications or for the implementation of other fiber optic devices. The main characteristics of these molecularly self-assembled optical fiber sensors are their negligible temperature dependence, their fast response and the possibility of using low cost LEDs instead of lasers or even the possibility of operating at different wavelengths.
