The tunabilities are based on the index modulation capable of being varied in the corrugated structure under externally applied mechanical forces. The new type of fiber filter enables wavelength and loss tuning ranges of more than 40 nm and 25 dB by adjusting the applied amounts of torsion and tensile forces, respectively. |
