  • Enhanced sensitivity fibre optic long period grating temperature sensor. 
    Khaliq, Sarfraz; James, Stephen W.; Tatam, Ralph P. (Iop Publishing Ltd, 2002-05-05)
    Surrounding a long period grating, fabricated in a standard optical fibre, with a material with a high thermo-optic coefficient enhances the temperature sensitivity of a long period grating. Temperature sensitivities as ...
  • Fibre-optic long period gratings for sensing applications 
    Khaliq, Sarfraz (Cranfield University, 2003-03)
    Long period gratings (LPGs) are formed by inducing a permanent periodic modulation of the refractive index (RI) of the core of an optical fibre. The transmission spectrum of the LPG contains a series of attenuation bands ...
