The concern for Sensing Application using photonic crystal had become an elevation in diverse field. Enhanced precision in sensing became an anticipation of users. Photonic crystal fibers are considered to be eccentric than optical fiber sensors due to its geometric structures. By proposing novelty in geometric structures of PCF can increase the sensitivity range as per the required application. In this paper we made a review on different sensors like physical , Curvature, Displacement, Electric and magnetic field, Refractive Index , Bio chemical, Biomedical which are used for sensing applications .
