Abstract

This work describes the suitability of a nano-dimension slot with low index material in the core region to achieve a highly nonlinear, polarization maintaining and dispersion compensating photonic crystal fiber. Our design is composed of a spiral shaped photonic crystal fiber with an elliptical slot made of silicon nanocrystals in the core region. The simulated results show that high nonlinear coefficients at the 1.55 μm wavelength for quasi-TE mode and quasi-TM mode are found to be equal to 1348 and 638 W–1m–1, respectively. The proposed design offers high birefringence up to 0.2503 and large negative dispersion value –1228 ps/nm/km. The proposed fiber has immense potential for realization of all-optical signal processing devices/networks and sensing applications while maintaining its polarization.
