Abstract
In this work, a low-cost temperature sensor based on step-index optical fibers with a slanted surface at the distal is fabricated and tested. Distal ends of a series of optical fibers are mechanically polished to obtain slanted surfaces at 45°, 30°, and 22.5° and are tested in a sensor in the temperature range from 20 °C to 220 °C, exhibiting a spectral response to temperature with sensitivities of up to 21.5 pm/°C.
