Title

Avoided-Crossing-Based Liquid-Crystal Photonic-Bandgap Notch Filter

Abstract

We demonstrate a highly tunable deep notch filter realized in a liquid-crystal photonic-bandgap (LCPBG) fiber. The filter is realized without inducing a long-period grating in the fiber but simply by filling a solidcore photonic-crystal fiber with a liquid crystal and exploiting avoided crossings within the bandgap of the LCFBG fiber. The filter is demonstrated experimentally and investigated using numerical simulations. A high degree of tuning of the spectral position of the deep notch is also demonstrated. © 2008 Optical Society of America.
