Over the past decade, photonic crystal fibers (PCFs) have attracted the attention of researchers for their applications in optical communications as a transmission medium. The question is: by considering latest research outcomes on PCFs, what is your outlook on the application popularity of this type of fiber?
These fibres are expected to eliminate the limitations set by the materials and designs of conventional fibres.Due to the large index diifference between air and silica, the properties of these fibres can theoretically be engineered to the extremes.
By changing the structural parameters of the fibre, either extremely low or high values of effective area, dispersion or nonlinearity can be obtained.
Moreover, large birefringence, endlessly single mode operation and resilience to bending loss can also be achieved. These unique possibilities make PCFs very attractive for several applications, including optical communication systems.
