摘要：

D-shaped optical fiber microwire (OFM) devices are investigated theoretically. They can be obtained by wrapping OFMs on removable rods or laying the OFMs on disposable substrates. Optical wave guiding properties of these devices are discussed with numerical simulations. Dispersion properties of OFMs with different radii are studied as well. A grating-based D-shaped OFM is proposed for sensing applications. The corresponding sensitivity could reach 1100 nm/RIU (refractive index unit) due to its large outside evanescent field.
