چکیده

An optical fiber transducer able to work in high temperature environments is experimentally demonstrated in the laboratory. It is based on a permanent long period grating (LPG) written using a new technique based on a thermo-mechanical approach. Device precision was experimentally checked by means of repetitive thermal cycles between 25 and 950 °C. In addition device stability was assured by maintaining the temperature in steady state at 800 °C during 23 hours.

Negative Temperature Response of LPGs Written in B-Ge Co Doped Photosensitive Fiber

In this paper, the effects of temperature on the spectral profiles of long period grating (LPG) fabricated in BGe co doped photosensitive fiber is investigated. The results obtained show that LPG in a B–Ge co doped fiber has negative temperature response or opposite sign of the temperature dependence compared with LPG written in standard telecommunication fiber . Keywords— Fiber grating, Long P...

In-fiber polarizer based on a long-period fiber grating written on photonic crystal fiber.

A novel in-fiber polarizer based on a long-period fiber grating (LPFG) is written by using a focused CO2 laser beam to notch a photonic crystal fiber periodically. Such a polarizer exhibits a high polarization extinction ratio of more than 20 dB over a wide wavelength range of ~11 nm near 1550 nm and a very low temperature sensitivity of 3.9 pm/ degrees C, which overcomes the disadvantages of t...

Thermal tuning of mechanically induced long-period fiber grating.

We have developed a wideband tunable optical filter that uses a long-period fiber grating (LPFG) in which both resonance wavelength and its signal attenuation can be adjusted. We create the grating mechanically by pressing a spring coil to an optical fiber. We achieve continuous fine tuning of wavelength and attenuation by varying the temperature of the LPFG. The adjustable ranges of the LPFG a...
