Multimode Optical Fiber Sensing
Abstract
The vast majority of fiber optic strain sensors use single mode fiber, yet multimode fiber offers many advantages. Multimode fiber has a higher nonlinear threshold which enables higher light levels and lower noise while the diversity of spatial modes can be used to develop sensors that are inherently immune to signal fading. All of these advantages can help to decrease noise levels and increase sensing capabilities. In my research conducted during my Karles fellowship, I built sensors that exploited these advantages to develop new sensing architectures. The sensors presented here achieved a linear strain response, pico-strain-level noise floor, and kHz of bandwidth.
