Characteristics of magneto-optic fiber Bragg gratings for use in...

The characteristics of photonic bandgaps and the transmission/reflection of guided optical waves in the magneto-optic fiber Bragg grating (MFBG) are theoretically investigated for the first time. The polarization-mode conversion resulting from the Faraday effect may change the width of the pure bandgap, or even lead to a couple of photonic semitransparent frequency band (STB) for sufficiently large magneto-optical-to-grating coupling ratio (MGR). Within the STBs, the transmittivity and reflectiv
