Abstract

We demonstrate a two-mode elliptical-core fiber strain sensorremotely interrogated over lead-insensitive single-mode fiber using pseudo- heterodyne demodulation. In addition, preliminary results obtaineddemonstrate FMCW multiplexing of two elliptical-core fiber sensors in a'single-fiber' configuration.
