Abstract
A low-cost temperature sensor using D-shaped optical fiber with 1.7m long, highly concentrated erbium-doped fiber as the gain medium, has been experimentally demonstrated. The D-shaped optical fiber was polished using a 5V DC motorized mechanical wheel and interacted with surrounding temperature varying from room temperature to $70^{\circ}$ C. Due to the temperature changes, the wavelength shifted to a longer region. This sensor has a sensitivity and linearity of 8.6 $\mathrm{x}10-3$ dBm/% and 94%, respectively. By using a simple fiber ring laser cavity, a sensitive and stable temperature sensor was successfully achieved.
