Temperature sensors based on Quantum Dots (QDs) nanofilms deposited on the inner holes of a Photonic Crystal Fiber (PCF) was created using the layer by layer electrostatic self-assembly method. The structure is based on a PCF fiber segment spliced between two Standard Multimode Fibers (MMF) of different diameters. The sensors showed a linear variation of the intensity and wavelength emission for a temperature range from -20 ºC to 70 ºC.

Photonic crystal fiber temperature sensor based on quantum dot nanocoatings
(Hindawi / Wiley, 2009) Larrión Zabaleta, Beatriz; Hernáez Sáenz de Zaitigui, Miguel; Arregui San Martín, Francisco Javier; Goicoechea Fernández, Javier; Bravo Larrea, Javier; Matías Maestro, Ignacio; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
Quantum dot nanocoatings have been deposited by means of the Layer-by-Layer technique on the inner holes of Photonic Crystal Fibers (PCFs) for the fabrication of temperature sensors. The optical properties of these sensors including absorbance, intensity emission, wavelength of the emission band, and the full width at half maximum (FWHM) have been experimentally studied for a temperature range from -40 to 70ºC.
