Abstract

We develop an intuitive understanding for the various properties and guiding mechanism of M-type fibers. We also report the approximate expression for the V-parameter (normalized frequency) to predict the modal-cutoffs for the M-type fibers, for the first time. This work demonstrates the potential of the M-type fibers for novel applications such as tailoring the transmission spectrum of photonic bandgap fibers, bend-induced effective area reduction for non-linear applications, and all-fiberized filters.
