摘要：

We report a simple and compact wavelength-encoded high-temperature sensor. It consists of a microstructured silica fiber taper with collapsed air holes in the waist. The transmission spectra of the taper exhibits a series of interference peaks owing to the beating between several modes of the solid taper waist. The interference peaks shift to longer wavelengths as the temperature increases from 200 degrees C to 1000 degrees C. The sensor exhibits a linear response and can be operated with different wavelengths which makes it attractive for diverse applications.
