OptiFiber uses numerical mode solvers and other models specialized to fibers for calculating dispersion, losses, birefringence, and PMD.
KEY APPLICATIONS of OptiFiber :
◦Assess parameters, sensitivities, and tolerances
◦Fiber mode solving of LP or Vector modes by Finite Difference or by Transfer Matrix Methods
◦Analysis of measured fiber profiles from instruments such as the EXFO NR-9200
◦Single mode fiber designs such as Corning SMF-28, dispersion flattened or shifted fibers.
◦Multimode fiber design, such as 50/125 m and 62.5/125 m silica fibers.
◦Visualization of multimode interference patterns with propagation
◦Automatic parameter scanning
◦Fiber Sensor design
◦Calculation of birefringence and PMD from intrinsic or extrinsic perturbations

Question:
I want to simulate the transparency of a photonic crystal fiber. For example, I am trying to design a fiber so that there is a small range of wavelengths that will be able to propagate. Is this an OptiFDTD application?
Answer:
OptiFDTD is, as you suggested, the most suitable software for this purpose. You can define a small section of fiber within the software and calculate the transmission and reflection spectra. You can then define geometrical parameters in your design and perform parameter sweeps to fine tune the fiber spectrum.
