Enhancement of strain sensor sensitivity by combination of polarization maintaining fiber and single mode fiber in sagnac loop

Optical fiber-based sensing. techniques provide a unique set. of sensors which are small, easy to fabricate, lightweight, immune to electromagnetic interference (EMI), high sensitivity, large scale multiplexing, and in most cases inexpensive to manufacture. These advantages are the motivation behind...

Based on the experimental result, strain elements of 10 cm PMF, 20 cm PMF, 36 cm PMF + 4 cm SMF and 36 cm PMF + 14 cm SMF records sensitivities of 6.4 pm/μɛ, 14.7 pm/μɛ, 22.8 pm/μɛ and 25.3 pm/μɛ correspondingly for a range 0-1000 μɛ at 25 Cº temperature. It shows that the strain element of 36 cm PMF + 14 cm SMF possesses the highest sensitivity. In addition to the experimental results, simulation work is also done for comparison.
