Abstract
A fiber-inline MZI device for temperature sensing or refractive index (RI) sensing, the device comprising: a section of a Photonic Crystal Fiber (PCF) having at least two air holes infiltrated with a liquid analyte to form a waveguide channel, the liquid analyte forming rods in the PCF; wherein the rods leave an interference fringe pattern in the transmission spectrum when light is injected into the PCF, and fringe dips are tracked over a wide wavelength range in order to sense the temperature or refractive index.
