An optical fiber for measuring pressure comprising a core for guiding optical signals along a length of the core and a cladding layer including a plurality of stress applying parts disposed around the core. The plurality of stress applying parts are disposed parallel to and symmetrically around the core to induce intensified symmetric shear stress upon application of external pressure while preventing birefringence. The optical fiber provides improved strain sensitivity compared to a standard single-mode optical fiber.
