A compact all-fiber optical anemometer based on a fiber Bragg grating inscribed in a metal-filled microstructured optical fiber (MOF) is presented. Six-hole MOF (SHMOF) with a suspended core is fabricated to engineer the evanescent field of the fundamental guided mode, and low-melting-point alloy is...
