We demonstrated a fast mechanical wheel lapping technique to fabricate a convenient and low-cost side-polished fiber (SPF) with a rough, rather than smooth, polished surface. Such a bare SPF can be directly used to develop a promising sensing device, because a Mach-Zehnder interference pattern with high fringe contrast above 10 dB in transmission spectrum was achieved due to the macro scratches on the rough polished surface. Fabrication parameters, e.g., thickness of remaining fiber, polished length, and roughness of abrasive paper, were optimized. The sensor exhibited strain and temperature sensitivities up to -2.00 pm/με and 29.37 pm/°C and can be used to realize simultaneous strain and temperature measurement.
