- Abstract
- A single-mode fiber (SMF) acousto-optic tunable filter (AOTF) with a tuning range of more than 300nm is demonstrated. The SMF used in the experiment has a ring of symmetric holes within the cladding, which causes a larger mode-index difference between the first and the second higher-order antisymmetric modes than those of a conventional SMF. As a result, the difference in beatlengths between the core mode and the higher-order modes is highly increased, which makes it possible for the SMF AOTF to exhibit a single resonance peak in the transmission spectrum over the wavelength range of 1: 3-1:6 mu m for given acoustic frequencies of 3: 1-3:8 MHz.
