Based on deep understanding on the relation between the properties of biconical fibers and the fusion temperature, a problem of fusion temperature monitoring is solved by means of a ceramic microheater and a fiber pyrometer. Effects of the fusion temperature on optical properties of biconical fibers are studied quantitatively. Biconical fiber devices with various filtering spectra are fabricated. Experimental results agree well with theoretical predictions.
