Description: photonic crystal fiber (PCF) made of silicon is proposed and numerically
optimized with both ultrahigh birefringence and nonlinearity. By introducing an elliptical lowindex
slot in the core region, one of the orthogonally polarized fundamental modes can be
confined in the low-index region due to the discontinuity of its electric field at the interface of
the slot and the surrounding material, while the other fundamental mode is dominated by the
modified total internal reflection (MTIR) induced by air holes of the cladding, leading to a
birefringence as high as 101 order. On the other hand, benefiting the tight field
confinement and highly nonlinear material, nonlinear coefficients up to 1068 W1 m1 and
162 W1 m1 can be achieved for the slot mode and the MTIR mode, respectively.-photonic crystal fiber (PCF) made of silicon is proposed and numerically
