Abstract

We report the first high-quality POFBG (uniform and phase shifted-POFBGs) sensors inscribed with only one KrF laser pulse at 850 nm region. The devices have been inscribed in a PMMA fibre, with a core doped with BDK for photosensitivity enhancement. The produced Bragg structure rejects more than 16 dB transmitted power, providing ~98% reflectivity, which is well suited for sensing/optical communication applications. The ability to inscribe these high-quality sensors effectively can significantly reduce their production cost in industry. Importantly, the inscription process reported here could be used during the POF drawing process, for simultaneous fabrication of the fibre and POFBG devices.
