“…The Bragg wavelength exhibited a linear response over the strain range 0-3%, with a sensitivity of 0.701 ± 0.003pm/µε calculated by linear regression. This sensitivity is very close to the value of 0.71 pm/µε reported for PMMA 3-ring mPOFBGs at 850nm [49] and 827nm [50], and similar to that of 0.64 pm/µε measured for a TOPAS 2-ring mPOFBG at 870 nm [13]. Moreover, the fiber did not show any hysteresis in the unloading phase, since the forward and reverse curves were perfectly overlapped, as shown in Fig.…”

Abstract:Here we present the fabrication of a solid-core microstructured polymer optical fiber (mPOF) made of polycarbonate (PC), and report the first experimental demonstration of a fiber Bragg grating (FBG) written in a PC optical fiber. The PC used in this work has a glass transition temperature of 145°C. We also characterize the mPOF optically and mechanically, and further test the sensitivity of the PC FBG to strain and temperature. We demonstrate that the PC FBG can bear temperatures as high as 125°C without malfunctioning. In contrast, polymethyl methacrylate-based FBG technology is generally limited to temperatures below 90°C. ©2016 Optical Society of America

“…The noise level is 16 dB lower than the peak power. For SM POF (MORPOF02) FBG at 850 nm we achieve a 3 dB bandwidth of 0.095 nm, which is less than the previously published results 9 . At the 1550 nm wavelength range, both multimode mPOF FBGs display similar peak powers for the same exposure time however the 3 dB bandwidth is 0.15 nm for the MM mPOF G3 (Fig.…”

We report on the production and characterization of narrow bandwidth fiber Bragg gratings (FBGs) in two spectral regions using polymer optical fibers (POFs). Narrow bandwidth FBGs are increasingly important for POF transmission systems, WDM technology and sensing applications. Long FBGs with resonance wavelength around 850 nm and 1550 nm were fabricated in several types of polymer optical fibers. The 3 dB FBG bandwidth varies from 0.22 nm down to 0.045 nm considering a Bragg grating length of 10 mm and 25 mm, respectively.

“…An appropriate wavelength regime is around 650 nm, where PMMA has low material loss, but the more common wavelength for POFBGs is around 850 nm, which we will also focus on here [26,27], since the polymer presents high losses at the 1550 nm region [27]. Conventionally, the inscription of POFBGs is made with the phase mask technique using continuous wave (CW) 325 nm HeCd UV lasers [25].…”
