• An intrinsic, exposed core, optical fibre sensor has been used for directly monitoring surface crystal growth in-situ. A negative, linear relationship (R2=0.98, n =44) was observed between radial loss of radiation at sites of crystal growth and radiation transmitted along the fibre as guided modes. A positive, linear response (R2=0.99, n =8) was also observed between measured crystal thickness (on the surface of the fibre core) and attenuation of radiation guided within the fibre. An empirical geometric ray-model, based on the refraction of guided modes out of the exposed fibre core into the crystals of higher refractive index supported the experimental observations. Results point to the potential of using an optical fibre as a fully-recoverable, quantitative sensor of crystal growth.
