Abstract:
We demonstrate the cascading of biconical fiber tapers as a simple method for converting monomode optical fibers into wavelength filters with a prescribed response. As an example, we made a narrow-bandpass filter consisting of four biconical tapers of different elongations made in succession on a single fiber. The transmission peak of the spectral response of the filter is centered on an arbitrary wavelength within the monomode domain of the fiber. The half-power width is approximately 6 nm.
