Paper Abstract

A unique all-fiber tunable filter is based on the combination of a single resonant band long period grating (LPG) and an electro-optic polymer second cladding layer. The single resonant band LPG is fabricated by etching the cladding of a 125 μm thick fiber and using ultraviolet (UV) illumination to write the grating. Once a single resonant band has been achieved, an ITO electrode is sputtered onto the thin silica cladding and then a polymer second cladding layer is applied. The refractive index of the polymer determines the resonant wavelength of the filter. After a second electrode is coated onto the second cladding, the polymer index is tuned by applying an external electric field. Recent modeling and experimentation has shown that a high index ITO inner electrode can increase the tuning range of the filter up to 10 times by inducing cladding mode transitions.
