Abstract
The coupling characteristics of newly proposed hollow optical fiber (HOF) couplers are rigorously analyzed using the compact 2-D finite-difference time-domain (FDTD) method. The FDTD-simulated coupling efficiency as a function of the coupling length, and the transverse electric field distributions of the higher-order mode converted by the HOF couplers, are investigated. We propose that the designed HOF couplers can be used for various optical devices such as side-pumping doubleclad fibers, mode splitters, and power monitors.
