Bent and etched optical fiber sensors have increased sensing capabilities but they are very much prone to fracture and breakage. The proposed sensor is stable showing very less tendency towards any breakage or fracture. The sensitivity of the sensor is tested for glycerin with different concentrations. It is evident from the experimental results that with the increase of glycerin concentration the output intensity of the sensor is decreased linearly. The proposed sensor may find applications in detecting various chemical species and biochemical applications.
