Abstract

The modal cutoff properties in a germanium-doped solid-core photonic-crystal fiber Bragg grating (PCFBG) are investigated with the beam propagation method. The results show that the normalized frequency V of a PCFBG depends not only on the normalized pitch Λ λ but also on the normalized hole size d Λ . In addition, the single-mode–multimode boundary profile of the PCFBG shifts to the low normalized hole-size side in contrast to that of the pure-silica solid-core photonic-crystal fiber (pure-solid PCF). Furthermore, besides the phase-matching condition and the electric field overlapping with the grating region, the inequality V PCF > π also should be fulfilled for the higher-order resonant modes to be excited in the PCFBG.
