A Few Mode Fiber Temperature Sensor Filled With PDMS Based on Vernier Effect

IEEE Photonics Journal, 2021
A few mode fiber temperature sensor filled with PDMS based on vernier effect is proposed. It uses single mode fiber (SMF), few mode fiber (FMF), and polydimethylsiloxane (PDMS) to form the SMF-air microcavity-FMF-PDMS-FMF structure.
