A theoretical analysis of a fiber optical photonic band gap based
tunable wavelength filter is presented. The design presented here is based on
the quarter wave reflector with a liquid crystal defect layer in the middle of
the structure. The filter generated by the structure is shifted in wavelength
as the voltage applied to the structure is modified. Some critical parameters
are analyzed: the effect of the consideration of fiber as the first layer and not
the input medium in the shape of the filter, the number of layers of the
structure, and the thickness of the defect layer. This last parameter
determines the width of the wavelength sweep of the filter, but is limited by
the creation of more defects. Some rules of practical implementation of this
device are also given. [--]
