Abstract
Directional mode coupling in an asymmetric holey fiber coupler is demonstrated both numerically and experimentally for the first time. The holey fiber mode couplers have interesting spectral characteristics and are also found to exhibit increased dimensional tolerances. Following a design based on numerical investigations, a dual-core polymer holey fiber coupler for LP01 and LP11 mode multiplexing was fabricated via a drilling and drawing technique. The measurements are compared with the simulation results.
