Quasi single mode fiber as a temperature sensor - art. no. 61891G
Original language description
Quasi single mode fiber is a fiber supporting a few modes only. If the operational wavelength of the light source will be shorter than the cut-off wavelength is, then the fiber will support except fundamental mode LP01 several higher modes too. Such fiber conserve themselves the advantageous characteristics for telecommunication application (small attenuation, slight dispersion), but it is possible to use them for sensor-based applications utilizing the mode coupling among several guided modes. This paper describes design of optical fiber working as a conventional telecommunication fiber at wavelength of 1550 nm and temperature sensing fiber at the wavelength of 850 ran. In the paper the basic theory together with the simulation of the mode distribution will be shown temperature changes within the interval 20 degrees C-100 degrees C.
