- A single-mode fiber (SMF) acousto-optic tunable filter (AOTF) with a tuning range of more than 300 nm 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 μm for given acoustic frequencies of 3.1–3.8 MHz.
