Characterisation of Silicon (Si) fibre Bragg grating in near-infrared band for strain and temperature sensing
Theodosiou, Antreas; Kalli, Kyriacos; Hawkins, Thomas A.; Ballato, John; Fokine, Michael; Gibson, Ursula (Journal article; Peer reviewed, 2018)This letter describes fibre Bragg grating inscription in crystalline siliconcore fibre using visible light femtosecond laser pulses. The femtosecond pulses at 517 nm propagate through the transparent silica glass cladding ... -
Laser structuring, stress modification and Bragg grating inscription in silicon-core glass fibers
Fokine, Michael; Theodosiou, Antreas; Song, Seunghan; Hawkins, Thomas A.; Ballato, John; Kalli, Kyriacos; Gibson, Ursula (Journal article; Peer reviewed, 2017)Semiconductor core fibers have numerous potential applications in optoelectronics and photonics, and the key to realizing these opportunities is controlled processing of the material. We present results on laser treatments ...
